curl_global_init - Global libcurl initialisation

.SH SYNOPSIS

.SH DESCRIPTION
|
|
|
|
|
This function should only be called once (no matter how many threads or
|
|
|
|
|
libcurl sessions that'll be used) by every application that uses libcurl.
|
|
|
|
|
|
2004-02-27 10:34:06 -05:00
|
|
|
If this function hasn't been invoked when \fIcurl_easy_init(3)\fP is called,
|
2005-12-23 18:22:23 -05:00
|
|
|
it will be done automatically by libcurl. It is adviced that you do not rely
|
|
|
|
|
on this automatic call, but instead call \fIcurl_global_init(3)\fP properly.
|
2002-03-04 05:09:48 -05:00
|
|
|
|
|
|
|
|
The flags option is a bit pattern that tells libcurl exact what features to
|
|
|
|
|
init, as described below. Set the desired bits by ORing the values together.
|
|
|
|
|
|
2004-02-27 10:34:06 -05:00
|
|
|
You must however \fBalways\fP use the \fIcurl_global_cleanup(3)\fP function,
|
|
|
|
|
as that cannot be called automatically for you by libcurl.

|
|
|
Calling this function more than once will cause unpredictable results. If that
|
|
|
|
|
is not enough, calling this function from more than one thread may also cause
|
|
|
|
|
unpredictable results.
