NAME
gnutls_global_init - This function initializes the global data to
defaults.
SYNOPSIS
#include <gnutls/gnutls.h>
int gnutls_global_init( void);
ARGUMENTS
void
DESCRIPTION
This function initializes the global data to defaults. Every gnutls
application has a global data which holds common parameters shared by
gnutls session structures. You must call gnutls_global_deinit() when
gnutls usage is no longer needed Returns zero on success.
Note that this function will also initialize libgcrypt, if it has not
been initialized before. Thus if you want to manually initialize
libgcrypt you must do it before calling this function. This is useful
in cases you want to disable libgcrypt's internal lockings etc.
This function increment a global counter, so that
gnutls_global_deinit() only releases resources when it has been called
as many times as gnutls_global_init(). This is useful when GnuTLS is
used by more than one library in an application. This function can be
called many times, but will only do something the first time.
Note! This function is not thread safe. If two threads call this
function simultaneously, they can cause a race between checking the
global counter and incrementing it, causing both threads to execute the
library initialization code. That would lead to a memory leak. To
handle this, your application could invoke this function after aquiring
a thread mutex. To ignore the potential memory leak is also an option.
