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);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
cfree(): _BSD_SOURCE || _SVID_SOURCE
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.
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."
RETURN VALUEThe 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.
ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7).
