cfree - free allocated memory
#include <stdlib.h> /* In SunOS 4 */ int cfree(void *ptr); /* In glibc or FreeBSD libcompat */ void cfree(void *ptr); /* In SCO OpenServer */ void cfree (char * ptr, unsigned num, unsigned size); /* In Solaris watchmalloc.so.1 */ void cfree(void *ptr, size_t nelem, size_t elsize);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
cfree(): Since glibc 2.19: _DEFAULT_SOURCE Glibc 2.19 and earlier: _BSD_SOURCE || _SVID_SOURCE
This function should never be used. Use free(3) instead. Starting with version 2.26, it has been removed from glibc.
Other systems have other functions with this name. The declaration is sometimes in
<stdlib.h> and sometimes in
If you need it while porting something, add
#define cfree(p, n, s) free((p))
to your file.
An SCO manual writes: "The cfree routine is provided for compliance to the iBCSe2 standard and simply calls free. The num and size arguments to cfree are not used."
The SunOS version of cfree() (which is a synonym for free(3)) returns 1 on success and 0 on failure. In case of error,
errno is set to EINVAL: the value of
ptr was not a pointer to a block previously allocated by one of the routines in the malloc(3) family.
The cfree() function was removed from glibc in version 2.26.

The 3-argument version of cfree() as used by SCO conforms to the iBCSe2 standard: Intel386 Binary Compatibility Specification, Edition 2.
