NAME
       gnutls_x509_crq_get_extension_info - API function

SYNOPSIS
       #include <gnutls/x509.h>

       int gnutls_x509_crq_get_extension_info(gnutls_x509_crq_t crq, int indx, void * oid, size_t * sizeof_oid, unsigned int * critical);

ARGUMENTS
       gnutls_x509_crq_t crq
		   should contain a gnutls_x509_crq_t structure

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

       void * oid  a pointer to a structure to hold the OID

       size_t * sizeof_oid
		   initially holds the maximum size of	oid , on return holds actual size of  oid .

       unsigned int * critical
		   output variable with critical flag, may be NULL.

DESCRIPTION
       This  function  will return the requested extension OID in the certificate, and the critical flag for it.  The extension OID will be stored
       as a string in the provided buffer.  Use gnutls_x509_crq_get_extension_data() to extract the data.

       If the buffer provided is not long enough to hold the output, then  *  sizeof_oid  is  updated  and  GNUTLS_E_SHORT_MEMORY_BUFFER  will	be
       returned.

RETURNS
       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code in case of an error.  If your have reached the last extension
       available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.

SINCE
