| .SH NAME |
| curl_global_cleanup - global libcurl cleanup |
| .SH SYNOPSIS |
| .B #include <curl/curl.h> |
| .sp |
| .BI "void curl_global_cleanup(void);" |
| .ad |
| .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. |
| |
| \fBThis function is not thread safe.\fP 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 |
| \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. |
