gnutls_x509_crq_get_extension_by_oid(3)       gnutls	  gnutls_x509_crq_get_extension_by_oid(3)

NAME
       gnutls_x509_crq_get_extension_by_oid - get the specified extension

SYNOPSIS
       #include <gnutls/x509.h>

       int  gnutls_x509_crq_get_extension_by_oid(gnutls_x509_crq_t  cert,  const  char * oid, int
       indx, void * buf, size_t * sizeof_buf, unsigned int * critical);

ARGUMENTS
       gnutls_x509_crq_t cert
		   should contain a gnutls_x509_crq_t structure

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

       int indx    In case multiple same OIDs exist in the extensions, this  specifies	which  to
		   send. Use zero to get the first one.

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

       size_t * sizeof_buf
		   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 encoded, in the provided buffer.

RETURNS
       On success, GNUTLS_E_SUCCESS is returned, otherwise a negative value in case of an  error.
       If     the     certificate     does     not     contain	   the	   specified	extension
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.

SINCE
       2.8.0
