NAME

       gnutls_x509_crt_get_subject_alt_othername_oid - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int  gnutls_x509_crt_get_subject_alt_othername_oid(gnutls_x509_crt_t  cert, unsigned int seq, void * oid,
       size_t * oid_size);

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 * oid  is the place where the otherName OID will be copied to

       size_t * oid_size
                   holds the size of ret.

DESCRIPTION

       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_crt_get_subject_alt_name() returned GNUTLS_SAN_OTHERNAME.

       If   oid  is  null then only the size will be filled. The  oid returned will be null terminated, although
       oid_size will not account for the trailing null.

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
        ian_size is not large enough to hold the value.  In that case
        ian_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.
