If you did not already call \fIcurl_global_init(3)\fP, \fIcurl_easy_init(3)\fP does it automatically. This may be lethal in multi-threaded cases, since \fIcurl_global_init(3)\fP is not thread-safe, and it may result in resource problems because there is no corresponding cleanup. You are strongly advised to not allow this automatic behaviour, by calling \fIcurl_global_init(3)\fP yourself properly. See the description in \fBlibcurl\fP(3) of global environment requirements for details of how to use this function. .SH RETURN VALUE If this function returns NULL, something went wrong and you cannot use the other curl functions. .SH "SEE ALSO" .BR curl_easy_cleanup "(3), " curl_global_init "(3), " curl_easy_reset "(3)"
