/* The ptid struct is a collection of the various "ids" necessary
|
|
for identifying the inferior. This consists of the process id
|
|
(pid), thread id (tid), and other fields necessary for uniquely
|
|
identifying the inferior process/thread being debugged. When
|
|
manipulating ptids, the constructors, accessors, and predicate
|
|
declared in server.h should be used. These are as follows:
|
|
|
|
ptid_build - Make a new ptid from a pid, lwp, and tid.
|
|
pid_to_ptid - Make a new ptid from just a pid.
|
|
ptid_get_pid - Fetch the pid component of a ptid.
|
|
ptid_get_lwp - Fetch the lwp component of a ptid.
|
|
ptid_get_tid - Fetch the tid component of a ptid.
|
|
ptid_equal - Test to see if two ptids are equal.
|
|
|
|
Please do NOT access the struct ptid members directly (except, of
|
|
course, in the implementation of the above ptid manipulation
|
|
functions). */
