- .TH curl_global_cleanup 3 "17 Feb 2006" "libcurl 7.8" "libcurl Manual"
- .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.
