gnutls_crypto_mac_register2(3)

Usage

#include <gnutls/gnutls.h>

int gnutls_crypto_mac_register2(int priority, int version, gnutls_crypto_mac_st * s);

Arguments

`int priority`	is the priority of the mac interface
`int version`	should be set to `GNUTLS_CRYPTO_API_VERSION`
`gnutls_crypto_mac_st * s`	is a structure holding new interface's data

Overview

This function will register a mac interface to be used by gnutls. Any interface registered will override the included engine and by convention kernel implemented interfaces should have priority of 90. The interface with the lowest priority will be used by gnutls.

This function should be called before gnutls_global_init().

For simplicity you can use the convenience gnutls_crypto_mac_register() macro.

Returns

GNUTLS_E_SUCCESS on success, otherwise an error.
