gnutls_global_init(3) gnutls gnutls_global_init(3)
gnutls_global_init - API function
#include <gnutls/gnutls.h>
int gnutls_global_init( void);
void
Since GnuTLS 3.3.0 this function is no longer necessary to be
explicitly called. To disable the implicit call (in a library
constructor) of this function set the environment variable
GNUTLS_NO_IMPLICIT_INIT to 1.
This function performs any required precalculations, detects the
supported CPU capabilities and initializes the underlying
cryptographic backend. In order to free any resources taken by
this call you should gnutls_global_deinit() when gnutls usage is
no longer needed.
This function increments 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. It is thread safe since GnuTLS 3.3.0.
A subsequent call of this function if the initial has failed will
return the same error code.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
negative error code is returned.
