cfree(3) -- Linux man page
NAMEcfree - 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);
DESCRIPTIONThis function should never be used. Use free(3) instead.
1-arg cfreeIn glibc, the function cfree() is a synonym for free(3), "added for compatibility with SunOS".
3-arg cfreeSome 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() to free memory allocated with calloc(), or do I need cfree()? Answer: use free().
RETURN VALUEThe SunOS version of cfree() (which is a synonym for free()) 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() family.
CONFORMING TOThe 3-argument version of cfree() as used by SCO conforms to the iBCSe2 standard: Intel386 Binary Compatibility Specification, Edition 2.
