gnutls_x509_crq_get_subject_alt_name — API function

Synopsis

#include <gnutls/x509.h>

int gnutls_x509_crq_get_subject_alt_name(gnutls_x509_crq_t crq, unsigned int seq, void * ret, size_t * ret_size, unsigned int * ret_type, unsigned int * critical);

Arguments

gnutls_x509_crq_t crq
should contain a gnutls_x509_crq_t type
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 gnutls_x509_subject_alt_name_t name type
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_crq_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).

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 ret_size is not large enough to hold the value. In that case ret_size will be updated with the required size. If the certificate request does not have an Alternative name with the specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.

Since

2.8.0
