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 immediately with no action.

EXAMPLE


char *width = curl_getenv("COLUMNS");
if(width) {
/* it was set! */
curl_free(width);
}

AVAILABILITY

Always

RETURN VALUE

None
