NAME

       gnutls_x509_crq_get_extension_info - Get extension id and criticality

SYNOPSIS

       #include <gnutls/x509.h>

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

ARGUMENTS

       gnutls_x509_crq_t cert
                   should contain a gnutls_x509_crq_t structure

       int indx    Specifies which extension OID to send. Use zero 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.

       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 is returned, otherwise a negative value in
       case of an error.  If your have reached the  last  extension  available
       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.

SINCE

       2.8.0
