NAME
       gnutls_x509_crq_get_attribute_info - API function

SYNOPSIS
       #include <gnutls/x509.h>

       int gnutls_x509_crq_get_attribute_info(gnutls_x509_crq_t crq, int indx, void * oid, size_t * sizeof_oid);

ARGUMENTS
       gnutls_x509_crq_t crq
		   should contain a gnutls_x509_crq_t structure

       int indx    Specifies which attribute 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 .

DESCRIPTION
       This  function  will return the requested attribute OID in the certificate, and the critical flag for it.  The attribute OID will be stored
       as a string in the provided buffer.  Use gnutls_x509_crq_get_attribute_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
