.TH curl_global_init 3 "11 May 2004" "libcurl 7.12" "libcurl Manual"

.SH NAME
|
|
curl_global_init - Global libcurl initialisation
|
|
.SH SYNOPSIS
|
|
.B #include <curl/curl.h>
|
|
.sp
|
|
.BI "CURLcode curl_global_init(long " flags ");"
|
|
.ad
|
|
.SH DESCRIPTION
|
|
This function sets up the program environment that libcurl needs. Think of it
|
|
as an extension of the library loader.
|
|
|
|
This function must be called at least once within a program (a program is all
|
|
the code that shares a memory space) before the program calls any other
|
|
function in libcurl. The environment it sets up is constant for the life of
|
|
the program and is the same for every program, so multiple calls have the same
|
|
effect as one call.
|
|
|
|
The flags option is a bit pattern that tells libcurl exactly what features to
|
|
init, as described below. Set the desired bits by ORing the values together.
|
|
In normal operation, you must specify CURL_GLOBAL_ALL. Don't use any other
|
|
value unless you are familiar with it and mean to control internal operations of
|
|
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_init()\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 \fBlibcurl\fP(3) of global environment requirements for
|
|
details of how to use this function.
|
|
|
|
.SH FLAGS
|
|
.TP 5
|
|
.B CURL_GLOBAL_ALL
|
|
Initialize everything possible. This sets all known bits.
|
|
.TP
|
|
.B CURL_GLOBAL_SSL
|
|
Initialize SSL
|
|
.TP
|
|
.B CURL_GLOBAL_WIN32
|
|
Initialize the Win32 socket libraries.
|
|
.TP
|
|
.B CURL_GLOBAL_NOTHING
|
|
Initialise nothing extra. This sets no bit.
|
|
.SH RETURN VALUE
|
|
If this function returns non-zero, something went wrong and you cannot use the
|
|
other curl functions.
