        !            31: .SH DESCRIPTION
        !            32: This function releases resources acquired by \fIcurl_global_init(3)\fP.
        !            33: 
        !            34: You should call \fIcurl_global_cleanup(3)\fP once for each call you make to
        !            35: \fIcurl_global_init(3)\fP, after you are done using libcurl.
        !            36: 
        !            37: \fBThis function is not thread safe.\fP You must not call it when any other
        !            38: thread in the program (i.e. a thread sharing the same memory) is running.
        !            39: This doesn't just mean no other thread that is using libcurl.  Because
        !            40: \fIcurl_global_cleanup(3)\fP calls functions of other libraries that are
        !            41: similarly thread unsafe, it could conflict with any other thread that uses
        !            42: these other libraries.
        !            43: 
        !            44: See the description in \fIlibcurl(3)\fP of global environment requirements for
        !            45: details of how to use this function.
        !            46: .SH CAUTION
        !            47: \fIcurl_global_cleanup(3)\fP does not block waiting for any libcurl-created
        !            48: threads to terminate (such as threads used for name resolving). If a module
        !            49: containing libcurl is dynamically unloaded while libcurl-created threads are
        !            50: still running then your program may crash or other corruption may occur. We
        !            51: recommend you do not run libcurl from any module that may be unloaded
        !            52: dynamically. This behavior may be addressed in the future.
