SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_extension_oid(gnutls_x509_crt_t cert, int indx, void * oid, size_t * oid_size);

ARGUMENTS

       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

       int indx    Specifies which extension OID to send. Use (0) to get the first one.

       void * oid  a pointer to a structure to hold the OID (may be null)

       size_t * oid_size
                   initially holds the size of  oid

DESCRIPTION

       This  function  will  return  the  requested extension OID in the certificate.  The extension OID will be
       stored as a string in the provided buffer.

       The  oid returned will be null terminated, although  oid_size will not account for the trailing null.

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned.  If  you  have
       reached the last extension available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
