NAME <\/a> <\/h2>\ncfree \u2212 free allocated memory<\/p>\n
SYNOPSIS <\/a> <\/h2>\n#include <\/b><\/p>\n\/* In SunOS 4 bodies\/ usr\/
int cfree(void *<\/b>ptr<\/i>);<\/b><\/p>\n
\/* In glibc or FreeBSD libcompat bodies\/ usr\/
void cfree(void *<\/b>ptr<\/i>);<\/b><\/p>\n
\/* In SCO OpenServer bodies\/ usr\/
void cfree(char *<\/b>ptr<\/i>, unsigned<\/b> num<\/i>, unsigned<\/b> size<\/i>);<\/b><\/p>\n
\/* In Solaris watchmalloc.so.1 bodies\/ usr\/
void cfree(void *<\/b>ptr<\/i>, size_t<\/b> nelem<\/i>, size_t<\/b> elsize<\/i>);<\/b><\/p>\n
Feature Test Macro Requirements for glibc (see feature_test_macros<\/b>(7)):<\/p>\n
cfree<\/b>():
Since glibc 2.19:
_DEFAULT_SOURCE
Glibc 2.19 and earlier:
_BSD_SOURCE || _SVID_SOURCE<\/p>\nDESCRIPTION <\/a> <\/h2>\nThis function should never be used. Use free<\/b>(3) instead. Starting with version 2.26, it has been removed from glibc.<\/p>\n
1-arg cfree<\/b>
In glibc, the function cfree<\/b>() is a synonym for free<\/b>(3), “added for compatibility with SunOS”.<\/p>\n
Other systems have other functions with this name. The declaration is sometimes in <\/i> and sometimes in <\/i>.<\/p>\n3-arg cfree<\/b>
Some SCO and Solaris versions have malloc libraries with a 3-argument cfree<\/b>(), apparently as an analog to calloc<\/b>(3).<\/p>\n
If you need it while porting something, add<\/p>\n
#define cfree(p, n, s) free((p))<\/p>\n
to your file.<\/p>\n
A frequently asked question is “Can I use free<\/b>(3) to free memory allocated with calloc<\/b>(3), or do I need cfree<\/b>()?” Answer: use free<\/b>(3).<\/p>\n
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.”<\/p>\n
RETURN VALUE <\/a> <\/h2>\nThe SunOS version of cfree<\/b>() (which is a synonym for free<\/b>(3)) returns 1 on success and 0 on failure. In case of error, errno<\/i> is set to EINVAL<\/b>: the value of ptr<\/i> was not a pointer to a block previously allocated by one of the routines in the malloc<\/b>(3) family.<\/p>\nVERSIONS <\/a> <\/h2>\nThe cfree<\/b>() function was removed from glibc in version 2.26.<\/p>\nATTRIBUTES <\/a> <\/h2>\nFor an explanation of the terms used in this section, see attributes<\/b>(7).<\/p>\n\n\n<\/td>\n <\/td>\n <\/td>\n <\/td>\n <\/td>\n <\/td>\n<\/tr>\n \n<\/td>\n <\/td>\n <\/td>\n <\/td>\n <\/td>\n <\/td>\n<\/tr>\n<\/table>\n![\"Image](\"grohtml-1590931.png\")
