|
|
.SH SYNOPSIS

|
.nf
|

|

|
.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.
|
||
|
|

|
