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().
