.SH NAME
|
||
|
|
curl_free - reclaim memory that has been obtained through a libcurl call
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
void curl_free(void *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 makes this function return immediately
|
||
|
|
with no action.
|
||
|
|
.SH EXAMPLE
|
||
|
|
.nf
|
||
|
|
char *width = curl_getenv("COLUMNS");
|

|
|
if(width) {
|
||
|
|
/* it was set! */
|
||
|
|
curl_free(width);
|
||
|
|
}
