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.
