pfm_rls_cleanup - release clean-up handlers
Syntax
#include <idl/c/base.h>
#include <idl/c/pfm.h>
void pfm_$rls_cleanup(cleanup_record, status)
pfm_$cleanup_rec *cleanup_record;
status_$t *status;
Arguments
cleanup_record The clean-up record for the first clean-up handler to release.
status The completion status. If status is pfm_$bad_rls_order, it means that the caller attempted to release a clean-up han-
dler before releasing all handlers established after it. This status is only a warning; the intended clean-up handler
is released, along with all clean-up handlers established after it. If the completion status returned in is equal to
status_$ok, then the routine that supplied it was successful.
Description
The routine releases the clean-up handler associated with cleanup_record and all clean-up handlers established after it.
