Return

EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.

The major error codes are as follows.

As for the other return codes or the details, see "Return status of Data window function"

CNC option

For HSSB connection,

The extended driver/library function is necessary.

CNC parameter

This function is not related to CNC parameter.

CNC mode

This function can be used in any CNC mode.

Available CNC

Note) 0i-C does not support the HSSB function.

Example(C Language)

The following program reads all registration information of NC program,
and displays program number list.

#include "fwlib32.h"

#define BUFSIZE 100

void example()
{
        PRGDIR4 prg[BUFSIZE];
        short i, num;
        long top = 0;
        short ret;

        do {
                num = BUFSIZE;
                ret = cnc_rdprogdir4( h, 0, top, &num, prg );
                if ( ret == EW_NUMBER ) {
                        break;
                }
                if ( ret ) {
                        printf( "ERROR: %d\n", ret );
                        break;
                }
                for ( i = 0 ; i < num ; i++ ) {
                        printf( "O%d\n", prg[i].number );
                }
                top = prg[num-1].number + 1;
        } while ( num >= BUFSIZE );
}

Example(C#)

The following program reads all registration information of NC program,
and displays program number list.

            short ret;

            byte[] bytes = new byte[Marshal.SizeOf(prg) * BUFSIZE];
            IntPtr ptrWork = Marshal.AllocCoTaskMem(Marshal.SizeOf(prg));
