.SH NAME
curl_free - reclaim memory that has been obtained through a libcurl call
.SH SYNOPSIS
.nf
#include <curl/curl.h>
void curl_free(char *ptr);
.fi
.SH DESCRIPTION
curl_free reclaims memory that has been obtained through a libcurl call. Use
\fIcurl_free(3)\fP 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 \fIptr\fP will make this function return
immediately with no action.
.SH EXAMPLE
.nf
char *width = curl_getenv("COLUMNS");
if(width) {
/* it was set! */
curl_free(width);
}
.fi
.SH AVAILABILITY
Always
.SH RETURN VALUE
