<title>Description</title>
|
|
|
|
<para>The <structname>sd_bus_error</structname> structure carries information about a D-Bus error
|
|
condition, or lack thereof. The functions described below may be used to set and query fields in this
|
|
structure.
|
|
<itemizedlist>
|
|
<listitem><para>The <structfield>name</structfield> field contains a short identifier of an error. It
|
|
should follow the rules for error names described in the D-Bus specification, subsection <ulink
|
|
url="https://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names">Valid
|
|
D-Bus Names</ulink>. A number of common, standardized error names are described in
|
|
<citerefentry><refentrytitle>sd-bus-errors</refentrytitle><manvolnum>3</manvolnum></citerefentry>, but
|
|
additional domain-specific errors may be defined by applications.</para></listitem>
|
|
|
|
<listitem><para>The <structfield>message</structfield> field usually contains a human-readable string
|
|
describing the details, but might be <constant>NULL</constant>.</para></listitem>
|
|
</itemizedlist>
|
|
An unset <structname>sd_bus_error</structname> structure should have both fields initialized to
|
|
<constant>NULL</constant>, and signifies lack of an error, i.e. success. Assign
|
|
<constant>SD_BUS_ERROR_NULL</constant> to the structure in order to initialize both fields to
|
|
<constant>NULL</constant>. When no longer necessary, resources held by the
|
|
<structname>sd_bus_error</structname> structure should be destroyed with
|
|
<function>sd_bus_error_free()</function>.</para>
|
|
|
|
<para><function>sd_bus_error_set()</function> sets an error structure to the specified name and message
|
|
strings. The strings will be copied into internal, newly allocated memory. It is essential to free the
|
|
contents again when they are not required anymore (see above). Do not use this call on error structures
|
|
that have already been set. If you intend to reuse an error structure, free the old data stored in it
|
|
with <function>sd_bus_error_free()</function> first.</para>
|
|
|
|
<para><function>sd_bus_error_set()</function> will return an <varname>errno</varname>-like value (see
|
|
<citerefentry
|
|
project='man-pages'><refentrytitle>errno</refentrytitle><manvolnum>3</manvolnum></citerefentry>)
|
|
determined from the specified error name <parameter>name</parameter>. If <parameter>name</parameter> is
|
|
<constant>NULL</constant>, it is assumed that no error occurred, and <constant>0</constant> is returned.
|
|
If <parameter>name</parameter> is nonnull, a negative value is always returned. If
|
|
<parameter>e</parameter> is <constant>NULL</constant>, no error structure is initialized, but
|
|
<parameter>name</parameter> is still converted into an <varname>errno</varname>-style value.</para>
|
|
|
|
<para>Various well-known D-Bus errors are converted to well-known <varname>errno</varname> counterparts,
|
|
and the other ones to <constant>-EIO</constant>. See
|
|
<citerefentry><refentrytitle>sd-bus-errors</refentrytitle><manvolnum>3</manvolnum></citerefentry> for a
|
|
list of well-known error names. Additional error mappings may be defined with
|
|
<citerefentry><refentrytitle>sd_bus_error_add_map</refentrytitle><manvolnum>3</manvolnum></citerefentry>.
|
|
</para>
|
|
|
|
<para><function>sd_bus_error_set()</function> is designed to be conveniently used in a
|
|
<function>return</function> statement. If <parameter>message</parameter> is <constant>NULL</constant>, no
|
|
message is set. This call can fail if no memory may be allocated for the name and message strings, in
|
|
which case an <constant>SD_BUS_ERROR_NO_MEMORY</constant> error will be set instead and
|
|
<constant>-ENOMEM</constant> returned. </para>
|
|
|
|
<para><function>sd_bus_error_setf()</function> and <function>sd_bus_error_setfv()</function> are similar
|
|
to <function>sd_bus_error_set()</function>, but take a <citerefentry
|
|
project='man-pages'><refentrytitle>printf</refentrytitle><manvolnum>3</manvolnum></citerefentry> format
|
|
string and corresponding arguments to generate the <structfield>message</structfield> field.
|
|
<function>sd_bus_error_setf()</function> uses variadic arguments, and
|
|
<function>sd_bus_error_setfv()</function> accepts the arguments as a
|
|
<citerefentry
|
|
project='man-pages'><refentrytitle>va_arg</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
|
parameter list.</para>
|
|
|
|
<para><function>sd_bus_error_set_const()</function> is similar to
|
|
<function>sd_bus_error_set()</function>, but the string parameters are not copied internally, and must
|
|
hence remain constant and valid for the lifetime of <parameter>e</parameter>. Use this call to avoid
|
|
memory allocations when setting error structures. Since this call does not allocate memory, it will not
|
|
fail with an out-of-memory condition as <function>sd_bus_error_set()</function> may, as described
|
|
above. Alternatively, the <constant>SD_BUS_ERROR_MAKE_CONST()</constant> macro may be used to generate a
|
|
literal, constant bus error structure on-the-fly.</para>
|
|
|
|
<para><function>sd_bus_error_set_errno()</function> will immediately return <constant>0</constant> if the
|
|
specified error parameter <parameter>error</parameter> is <constant>0</constant>. Otherwise, it will set
|
|
<structfield>name</structfield> from an <varname>errno</varname>-like value that is converted to a D-Bus
|
|
error. <citerefentry
|
|
project='die-net'><refentrytitle>strerror_r</refentrytitle><manvolnum>3</manvolnum></citerefentry> will
|
|
be used to set <structfield>message</structfield>. Well-known D-Bus error names will be used for
|
|
<structfield>name</structfield> if applicable, otherwise a name in the <literal>System.Error.</literal>
|
|
namespace will be generated. The sign of the specified error number is ignored and the absolute value is
|
|
used implicitly. If the specified error <parameter>error</parameter> is non-zero, the call always returns
|
|
a negative value, for convenient usage in <function>return</function> statements. This call might fail
|
|
due to lack of memory, in which case an <constant>SD_BUS_ERROR_NO_MEMORY</constant> error is set instead,
|
|
and <constant>-ENOMEM</constant> is returned.</para>
|
|
|
|
<para><function>sd_bus_error_set_errnof()</function> and <function>sd_bus_error_set_errnof()</function>
|
|
are similar to <function>sd_bus_error_set_errno()</function>, but in addition to
|
|
<parameter>error</parameter>, take a <citerefentry
|
|
project='man-pages'><refentrytitle>printf</refentrytitle><manvolnum>3</manvolnum></citerefentry> format
|
|
string and corresponding arguments. The <structfield>message</structfield> field will be generated from
|
|
<parameter>format</parameter> and the arguments.
|
|
<function>sd_bus_error_set_errnof()</function> uses variadic arguments, and
|
|
<function>sd_bus_error_set_errnofv()</function> accepts the arguments as a
|
|
<citerefentry

project='man-pages'><refentrytitle>va_arg</refentrytitle><manvolnum>3</manvolnum></citerefentry>
|
|
parameter list.</para>
|
|
|
|
<para><function>sd_bus_error_get_errno()</function> converts the <structfield>name</structfield> field of
|
|
an error structure to an <varname>errno</varname>-like (positive) value using the same rules as
|
|
<function>sd_bus_error_set()</function>. If <parameter>e</parameter> is <constant>NULL</constant>,
|
|
<constant>0</constant> will be returned.</para>
|
|
|
|
<para><function>sd_bus_error_copy()</function> will initialize <parameter>dst</parameter> using the
|
|
values in <parameter>e</parameter>, if <parameter>e</parameter> has been set with an error value before.
|
|
Otherwise, it will return immediately. If the strings in <parameter>e</parameter> were set using
|
|
<function>sd_bus_error_set_const()</function>, they will be shared. Otherwise, they will be
|
|
copied. Before this call, <parameter>dst</parameter> must be unset, i.e. either freshly initialized with
|
|
<constant>NULL</constant> or reset using <function>sd_bus_error_free()</function>.</para>
|
|
|
|
<para><function>sd_bus_error_copy()</function> generally returns <constant>0</constant> or a negative
|
|
<varname>errno</varname>-like value based on the input parameter <parameter>e</parameter>:
|
|
<constant>0</constant> if it was unset and a negative integer if it was set to some error, similarly to
|
|
<function>sd_bus_error_set()</function>. It may however also return an error generated internally, for
|
|
example <constant>-ENOMEM</constant> if a memory allocation fails.</para>
|
|
|
|
<para><function>sd_bus_error_move()</function> is similar to <function>sd_bus_error_copy()</function>,
|
|
but will move any error information from <parameter>e</parameter> into <parameter>dst</parameter>,
|
|
resetting the former. This function cannot fail, as no new memory is allocated. Note that if
|
|
<parameter>e</parameter> is not set, <parameter>dst</parameter> is initialized to
|
|
<constant>SD_BUS_ERROR_NULL</constant>. Moreover, if <parameter>dst</parameter> is
|
|
<constant>NULL</constant> no operation is executed on it and resources held by <parameter>e</parameter>
|
|
are freed and reset. Returns a converted <varname>errno</varname>-like, non-positive error value.</para>
|
|
|
|
<para><function>sd_bus_error_is_set()</function> will return a
|
|
non-zero value if <parameter>e</parameter> is
|
|
non-<constant>NULL</constant> and an error has been set,
|
|
<constant>false</constant> otherwise.</para>
|
|
|
|
<para><function>sd_bus_error_has_name()</function> will return a
|
|
non-zero value if <parameter>e</parameter> is
|
|
non-<constant>NULL</constant> and an error with the same
|
|
<parameter>name</parameter> has been set,
|
|
<constant>false</constant> otherwise.</para>
|
|
|
|
<para><function>sd_bus_error_has_names_sentinel()</function> is similar to
|
|
<function>sd_bus_error_has_name()</function>, but takes multiple names to check against. The list must be
|
|
terminated with <constant>NULL</constant>. <function>sd_bus_error_has_names()</function>
|
|
is a macro wrapper around <function>sd_bus_error_has_names_sentinel()</function> that adds the
|
|
<constant>NULL</constant> sentinel automatically.</para>
|
|
|
|
<para><function>sd_bus_error_free()</function> will destroy
|
|
resources held by <parameter>e</parameter>. The parameter itself
|
|
will not be deallocated, and must be <citerefentry
|
|
project='man-pages'><refentrytitle>free</refentrytitle><manvolnum>3</manvolnum></citerefentry>d
|
|
by the caller if necessary. The function may also be called safely
|
|
on unset errors (error structures with both fields set to <constant>NULL</constant>),
|
|
in which case it performs no operation. This call will reset the
|
|
error structure after freeing the data, so that all fields are set
|
|
to <constant>NULL</constant>. The structure may be reused afterwards.</para>

<para><structname>sd_bus_error</structname> is not reference-counted. Users should destroy resources held

stack or passed in as function parameters, but they may also be allocated dynamically, in which case it

is the duty of the caller to <citerefentry

<title>Return Value</title>
|
|
|
|
<para>The functions <function>sd_bus_error_set()</function>, <function>sd_bus_error_setf()</function>,
|
|
and <function>sd_bus_error_set_const()</function> always return <constant>0</constant> when the specified
|
|
error value is <constant>NULL</constant>, and a negative errno-like value corresponding to the
|
|
<parameter>name</parameter> parameter otherwise. The functions
|
|
<function>sd_bus_error_set_errno()</function>, <function>sd_bus_error_set_errnof()</function> and
|
|
<function>sd_bus_error_set_errnofv()</function>, return <constant>0</constant> when the specified error
|
|
value is <constant>0</constant>, and a negative errno-like value corresponding to the
|
|
<parameter>error</parameter> parameter otherwise. If an error occurs internally, one of the negative
|
|
error values listed below will be returned. This allows those functions to be conveniently used in a
|
|
<constant>return</constant> statement, see the example below.</para>
|
|

|
<para><function>sd_bus_error_get_errno()</function> returns

<para><function>sd_bus_error_copy()</function> and <function>sd_bus_error_move()</function> return a

negative error value converted from the source error, and zero if the error has not been set. This

allows those functions to be conveniently used in a <constant>return</constant> statement, see the

|
|
negative converted <varname>errno</varname>-style value, or <constant>0</constant> if the error
|
|
parameter is <constant>NULL</constant> or unset. D-Bus errors are converted to the integral
|
|
<varname>errno</varname>-style value, and the mapping mechanism is extensible, see the discussion
|
|
above. This effectively means that almost any negative <varname>errno</varname>-style value can be
|
|
returned.</para>
