Linux manual pages	Section 3: Subroutines

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 structure
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.
