gnutls_x509_crt_get_subject_alt_name2(3)

NAME
gnutls_x509_crt_get_subject_alt_name2 - Get certificate's alternative name, if any

SYNOPSIS
#include <gnutls/x509.h>

int gnutls_x509_crt_get_subject_alt_name2(gnutls_x509_crt_t cert, unsigned int seq, void * ret, size_t * ret_size, unsigned int * ret_type, unsigned int * critical);

ARGUMENTS

gnutls_x509_crt_t cert
    should contain a gnutls_x509_crt_t structure

unsigned int seq
    specifies the sequence number of the alt name (0 for the first one, 1 for the second etc.)

void * ret
    is the place where the alternative name will be copied to

size_t * ret_size
    holds the size of ret.

unsigned int * ret_type
    holds the type of the alternative name (one of gnutls_x509_subject_alt_name_t).

unsigned int * critical
    will be non zero if the extension is marked as critical (may be null)

DESCRIPTION
This function will return the alternative names, contained in the given certificate. It is the same as gnutls_x509_crt_get_subject_alt_name() except for the fact that it will return the type of the alternative name in ret_type even if the function fails for some reason (i.e. the buffer provided is not enough). The return values are the same as with gnutls_x509_crt_get_subject_alt_name().
