                     27: .B #include <curl/curl.h>

                     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.
