.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.
