Subject: scm_must_free
Date: Thu, 22 Aug 2002 02:07:11 +0200 [thread overview]
Message-ID: <15716.11055.92865.675317@blauw.xs4all.nl> (raw)
Why does scm_must_free barf on freeing the null pointer?
free() frees the memory space pointed to by ptr, which
must have been returned by a previous call to malloc(),
calloc() or realloc(). Otherwise, or if free(ptr) has
already been called before, undefined behaviour occurs.
If ptr is NULL, no operation is performed.
