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
