gnutls_x509_crq_get_subject_alt_othername_oid3

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 otherName OID will be copied to

size_t * ret_size

holds the size of ret.

Overview

This function will extract the type OID of an otherName Subject Alternative Name, contained in the given certificate, and return the type as an enumerated element.

This function is only useful if gnutls_x509_crq_get_subject_alt_name() returned GNUTLS_SAN_OTHERNAME.

Returns

the alternative subject name type on success, one of the enumerated gnutls_x509_subject_alt_name_t. For supported OIDs, it will return one of the virtual (GNUTLS_SAN_OTHERNAME_*) types, e.g. GNUTLS_SAN_OTHERNAME_XMPP, and GNUTLS_SAN_OTHERNAME for unknown OIDs. 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 does not have an Alternative name with the specified sequence number and with the otherName type then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
