gnutls_x509_crt_get_subject_alt_name2(3)                                gnutls

NAME

gnutls_x509_crt_get_subject_alt_name2 - API function

SYNOPSIS

#include <gnutls/x509.h> int gnutls_x509_crt_get_subject_alt_name2(gnutls_x509_crt_t cert, unsigned int seq, void * san, size_t * san_size, unsigned int * san_type, unsigned int * critical);

ARGUMENTS

gnutls_x509_crt_t cert should contain a gnutls_x509_crt_t type unsigned int seq specifies the sequence number of the alt name (0 for the first one, 1 for the second etc.) void * san is the place where the alternative name will be copied to size_t * san_size holds the size of ret. unsigned int * san_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 san_type even if the function fails for some reason (i.e. the buffer provided is not enough).

RETURNS

the alternative subject name type on success, one of the enumerated gnutls_x509_subject_alt_name_t. It will return GNUTLS_E_SHORT_MEMORY_BUFFER if san_size is not large enough to hold the value. In that case san_size will be updated with the required size. If the certificate does not have an Alternative name with the specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
