.SH NAME

gnutls_global_init \- API function

.SH SYNOPSIS

.B #include <gnutls/gnutls.h>

.sp

.BI "int gnutls_global_init( " void ");"

.SH ARGUMENTS

.IP " void" 12

.SH "DESCRIPTION"

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 \fBGNUTLS_NO_EXPLICIT_INIT\fP 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 \fBgnutls_global_deinit()\fP 

when gnutls usage is no longer needed.

This function increments a global counter, so that

\fBgnutls_global_deinit()\fP only releases resources when it has been

called as many times as \fBgnutls_global_init()\fP.  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.

.SH "RETURNS"

On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned,

otherwise a negative error code is returned.

.SH "REPORTING BUGS"
