Memowrite - ESC character

[Otto]

Copying dbf-files with memoread/memowrit adds a chr(26) (ESC character) at the end of the file.
Could this cause problems?
How can I add this C function to my FWPPC program?

Thanks in advance
Otto

   bRetVal = ( hb_fsWriteLarge( fhnd, ( BYTE * ) hb_itemGetCPtr( pString ), ulSize ) == ulSize );

/* NOTE: CA-Clipper will not return .F. when the EOF could not be written. [vszakats] */
#if ! defined(OS_UNIX_COMPATIBLE)
{

{
BYTE byEOF = HB_CHAR_EOF;

   hb_fsWrite( fhnd, &byEOF, sizeof( BYTE ) );
   }
}
#endif

hb_fsClose( fhnd );
   }
}

hb_retl( bRetVal );
   }

We have never tried it. Please try it and let us know if it works, thanks

Just add that code that you have published to your PRG

Thank you, Antonio.

The dbf-files seems to work also with the ESC but to face no problems in future I prefer to copy without.

If I link the code I get following warnings:

c:\develop8\nextstb\mystb.c(13285) : warning C4129: 'd' : unrecognized character escape sequence
c:\develop8\nextstb\mystb.c(13285) : warning C4129: 'm' : unrecognized character escape sequence
* Application successfully built and all is working.

Regards,
Otto

Otto,

Those warnings are caused as Harbour output .C files use "\" for paths, though "\\" should be used.

You can safely ignore them.
