Return Value

#include <curl/curl.h>

CURLcode curl_global_init(long flags);

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(3) 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(3) function, as that cannot be called automatically for you by libcurl.

Calling this function more than once will cause unpredictable results.

CURL_GLOBAL_ALL
	Initialize everything possible. This sets all known bits.
CURL_GLOBAL_SSL
	Initialize SSL
CURL_GLOBAL_WIN32
	Initialize the Win32 socket libraries.
CURL_GLOBAL_NOTHING
	Initialise nothing extra. This sets no bit.

If this function returns non-zero, something went wrong and you cannot use the other curl functions.

curl_global_init_mem(3), curl_global_cleanup(3),
