CFREE(3) Linux Programmer's Manual CFREE(3)
NAME
cfree - free allocated memory
SYNOPSIS
#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(): _BSD_SOURCE || _SVID_SOURCE
DESCRIPTION
This function should never be used. Use free(3) instead.
1-arg cfree
In glibc, the function cfree() is a synonym for free(3), "added for compatibility with SunOS".
Other systems have other functions with this name. The declaration is sometimes in <stdlib.h> and sometimes in <malloc.h>.
3-arg cfree
Some SCO and Solaris versions have malloc libraries with a 3-argument cfree(), apparently as an analog to calloc(3).
If you need it while porting something, add
#define cfree(p, n, s) free((p))
to your file.
A frequently asked question is "Can I use free(3) to free memory allocated with calloc(3), or do I need cfree()?" Answer: use free(3).
An SCO manual writes: "The cfree routine is provided for compliance to the iBCSe2 standard and simply calls free. The num and size argu-
ments to cfree are not used."
RETURN VALUE
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.
CONFORMING TO
The 3-argument version of cfree() as used by SCO conforms to the iBCSe2 standard: Intel386 Binary Compatibility Specification, Edition 2.
