curl_free(3) libcurl Manual curl_free(3)
NAME
curl_free - reclaim memory that has been obtained through a libcurl
call
SYNOPSIS
#include <curl/curl.h>
void curl_free(char *ptr);
DESCRIPTION
curl_free reclaims memory that has been obtained through a libcurl
call. Use curl_free(3) instead of free() to avoid anomalies that can
result from differences in memory management between your application
and libcurl.
Passing in a NULL pointer in ptr will make this function return immedi-
ately with no action.
EXAMPLE
char *width = curl_getenv("COLUMNS");
if(width) {
/* it was set! */
curl_free(width);
}
AVAILABILITY
Always
RETURN VALUE
None
