curl_global_init(3) libcurl Manual curl_global_init(3)NAMEcurl_global_init - Global libcurl initialisation
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_global_init(long flags);
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.
If this function hasn't been invoked when curl_easy_init
is called, it will be done automatically by libcurl.
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.
You must however always use the curl_global_cleanup func-
tion, as that cannot be called automatically for you by
libcurl.
Calling this function more than once will cause unpre-
dictable results.
This function was added in libcurl 7.8.
FLAGS
CURL_GLOBAL_ALL
Initialize everything possible. This sets all known
bits.
CURL_GLOBAL_SSL
Initialize SSL
CURL_GLOBAL_WIN32
Initialize the Win32 socket libraries. (added in
libcurl 7.8.1)
CURL_GLOBAL_NOTHING
Initialise nothing extra. This sets no bit.
RETURN VALUE
If this function returns non-zero, something went wrong
and you cannot use the other curl functions.
