NAME

       gnutls_x509_crt_get_extension_by_oid2 - API function


SYNOPSIS

       #include <gnutls/x509.h>

       gnutls_x509_crt_get_extension_by_oid2(3) cert, const
       char * oid, unsigned indx, gnutls_datum_t  *  output,  unsigned  int  *
       critical);


ARGUMENTS

       gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

       const char * oid
                   holds an Object Identified in null terminated string

       unsigned indx
                   In  case  multiple  same OIDs exist in the extensions, this
                   specifies which to send. Use (0) to get the first one.

       gnutls_datum_t * output
                   will hold the allocated extension data

       unsigned int * critical
                   will be non-zero if the extension is marked as critical


DESCRIPTION

       This function will return the extension specified by  the  OID  in  the
       certificate.   The  extensions  will  be  returned  as  binary data DER
       encoded, in the provided buffer.


RETURNS

       On success, GNUTLS_E_SUCCESS (0)  is  returned,  otherwise  a  negative
       error  code is returned. If the certificate does not contain the speci-
       fied extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be  returned.
