# This is a valgrind suppressions file.

# Common patterns are for every allocation to be followed by one with
# nih_alloc_ref_new() inserted between the call to nih_alloc() and malloc()
# this is the reference object for that object.
#
# Also if the call is ever made within a TEST_ALLOC_FAIL loop, you'll also
# need a test with:
#   fun:realloc
#   fun:_test_realloc
#   fun:_test_malloc
# in between the nih_alloc() and malloc() calls.


# There is a slight overhead to using some parts of libnih in the form
# of a heap-allocated list head used to link all allocated structures
# by that component.
#
# They are allocated the first time that part of libnih is used by the
# static nih_*_init function; valgrind complains because they are not
# freed before exit, as there's little point to doing so.
