NAME

       curl_easy_init - Start a libcurl easy session

SYNOPSIS

       #include <curl/curl.h>

       CURL *curl_easy_init( );

DESCRIPTION

       This  function  must  be the first function to call, and it returns a CURL easy handle that you must use as input to other functions in the
       easy interface. This call MUST have a corresponding call to curl_easy_cleanup(3) when the operation is complete.

       If you did not already call curl_global_init(3), curl_easy_init(3) does it automatically.  This may  be	lethal	in  multi-threaded  cases,
       since curl_global_init(3) 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 curl_global_init(3) yourself properly.  See the description in
       libcurl(3) of global environment requirements for details of how to use this function.

RETURN VALUE

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

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
	 CURLcode res;
	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
	 res = curl_easy_perform(curl);
	 curl_easy_cleanup(curl);
       }

NAME

       curl_global_init - Global libcurl initialisation

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_global_init(long flags);

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.

       This function is not thread safe. You must not call it when any other thread in the program (i.e. a thread sharing the same memory) is run-
       ning.  This doesn't just mean no other thread that is using libcurl.  Because curl_global_init() 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 libcurl(3) of global environment requirements for details of how to use this function.

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.

       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.
