NAME

       gnutls_x509_crq_get_extension_by_oid2 - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int   gnutls_x509_crq_get_extension_by_oid2(gnutls_x509_crq_t   crq,  const  char  *  oid,
       unsigned indx, gnutls_datum_t * output, unsigned int * critical);

ARGUMENTS

       gnutls_x509_crq_t crq
                   should contain a gnutls_x509_crq_t type

       const char * oid
                   holds an Object Identifier in a null terminated string

       unsigned indx
                   In case multiple same OIDs exist in the extensions, this  specifies  which  to
                   get. 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 in  case  of
       an   error.    If   the   certificate   does   not   contain   the   specified   extension
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.

SINCE

       3.3.8
