gnutls_pkcs11_init — API function


#include <gnutls/pkcs11.h>

int gnutls_pkcs11_init(unsigned int flags, const char * deprecated_config_file);


unsigned int flags

An ORed sequence of GNUTLS_PKCS11_FLAG_*

const char * deprecated_config_file

either NULL or the location of a deprecated configuration file


This function will initialize the PKCS 11 subsystem in gnutls. It will read configuration files if GNUTLS_PKCS11_FLAG_AUTO is used or allow you to independently load PKCS 11 modules using gnutls_pkcs11_add_provider() if GNUTLS_PKCS11_FLAG_MANUAL is specified.

You don't need to call this function since GnuTLS 3.3.0 because it is being called during the first request PKCS 11 operation. That call will assume the GNUTLS_PKCS11_FLAG_AUTO flag. If another flags are required then it must be called independently prior to any PKCS 11 operation.


On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
