.SH NAME
|
||
|
|
curl_global_cleanup - global libcurl cleanup
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
void curl_global_cleanup(void);
|
||
|
|
.fi
|
||
|
|
.SH DESCRIPTION
|
||
|
|
This function releases resources acquired by \fIcurl_global_init(3)\fP.
|
||
|
|
|
||
|
|
You should call \fIcurl_global_cleanup(3)\fP once for each call you make to
|
||
|
|
\fIcurl_global_init(3)\fP, after you are done using libcurl.
|
||
|
|
|
||
|
|
This function is thread-safe since libcurl 7.84.0 if
|
||
|
|
\fIcurl_version_info(3)\fP has the CURL_VERSION_THREADSAFE feature bit set
|
||
|
|
(most platforms).
|
||
|
|
|
||
|
|
If this is not thread-safe, you must not call this function when any other
|
||
|
|
thread in the program (i.e. a thread sharing the same memory) is running.
|
||
|
|
This does not just mean no other thread that is using libcurl. Because
|
||
|
|
\fIcurl_global_cleanup(3)\fP calls functions of other libraries that are
|
||
|
|
similarly thread unsafe, it could conflict with any other thread that uses
|
||
|
|
these other libraries.
|
||
|
|
|
||
|
|
See the description in \fIlibcurl(3)\fP of global environment requirements for
|
||
|
|
details of how to use this function.
|
||
|
|
.SH CAUTION
|
||
|
|
\fIcurl_global_cleanup(3)\fP does not block waiting for any libcurl-created
|
||
|
|
threads to terminate (such as threads used for name resolving). If a module
|
||
|
|
containing libcurl is dynamically unloaded while libcurl-created threads are
|
||
|
|
still running then your program may crash or other corruption may occur. We
|
||
|
|
recommend you do not run libcurl from any module that may be unloaded
|
||
|
|
dynamically. This behavior may be addressed in the future.
|
||
|
|
