NAME
       gnutls_x509_crt_get_extension_by_oid - API function

SYNOPSIS
       #include	<gnutls/x509.h>

       int  gnutls_x509_crt_get_extension_by_oid(gnutls_x509_crt_t cert, const
       char * oid, unsigned indx, void * buf, size_t * buf_size, 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.

       void * buf  a pointer to	a structure to hold the	name (may be null)

       size_t *	buf_size
		   initially holds the size of	buf

       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 en-
       coded, in the provided buffer.

RETURNS
       On success, GNUTLS_E_SUCCESS (0)	is returned, otherwise a negative  er-
       ror code	is returned. If	the certificate	does not contain the specified
       extension GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
