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.
