curl_global_cleanup(3)          libcurl Manual          curl_global_cleanup(3)

NAME
       curl_global_cleanup - global libcurl cleanup

SYNOPSIS
       #include <curl/curl.h>

       void curl_global_cleanup(void);

DESCRIPTION
       This function releases resources acquired by _global_init&section=3">curl_global_init(3).

       You should call _global_cleanup&section=3">curl_global_cleanup(3) once for each call you make to
       _global_init&section=3">curl_global_init(3), after you are done using libcurl.

       This function is not thread safe. You must not call it when any other
       thread in the program (i.e. a thread sharing the same memory) is
       running.  This doesn't just mean no other thread that is using libcurl.
       Because _global_cleanup&section=3">curl_global_cleanup(3) 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 libcurl(3) of global environment requirements
       for details of how to use this function.

CAUTION
       _global_cleanup&section=3">curl_global_cleanup(3) 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.
