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.
