curl_free(3) Library Functions 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(void *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 makes this function return immediately with no action. PROTOCOLS This functionality affects all supported protocols EXAMPLE int main(void) { char *width = curl_getenv("COLUMNS"); if(width) { /* it was set */ curl_free(width); } } AVAILABILITY Added in curl 7.1 RETURN VALUE None SEE ALSO curl_easy_escape(3), curl_easy_unescape(3) libcurl 2026-08-27 curl_free(3)
