# This is a warning-suppression file for valgrind supplied by libproc
|
|
# to be used with the option: --suppressions=<path-for>/libproc.supp.
|
|
#
|
|
# Memory leak warnings will only be encountered when a multi-threaded
|
|
# program has called the 'procps_pids' interface. That's because this
|
|
# library employs heap based memory in a thread safe manner. However,
|
|
# such memory will not be freed until the address space is reclaimed.
|
|
#
|
|
# When a sibling thread using this 'procps_pids' API ends, or if some
|
|
# other thread in that address space calls 'pthread_cancel()' on such
|
|
# a thread, valgrind will warn that some memory is 'definitely lost'.
|
|
#
|
|
# The majority of warnings depend on the 'pids_item' enumerators that
|
|
# have been specified using 'procps_pids_new' or 'procps_pids_reset'.
|
|
#
|
|
# Single-threaded applications will not experience any such warnings.
|
