I'm cross developing a program in free pascal running FreeVision. When running
under Linux / Busybox; I'm attempting to mount a device to scan it for a set of
files. Since I'm running a TUI (Text User Interface); I cannot have the BusyBox
mount command printing failure information to the screen where it corrupts the
TUI. The pascal code:
Exec( '/bin/mount', '/dev/'+ aline +' /media/' + aline + ' &> /dev/null');
When running:
Exec( '/bin/mount', '/dev/'+ aline +' /media/' + aline );
I see "device busy" STDERR messages appear on the screen. However, when I try
to redirect using the ' &> /dev/null' it appears as tho the BusyBox executable
is being passed ' &> /dev/null' as a parameter and isn't taking it as the
appropriate redirection command.
I tried the following kludge instead:
var
OurPipe : Text;
popen( OurPipe, '/bin/mount /dev/'+ aline +' /media/' + aline, 'R');
Try
if (fpgeterrno=0) then Flush (OurPipe)
ELSE MessageBox ('mount pipe error ' + IntToStr(fpgeterrno), nil,
mfError or mfOKButton);
Finally
PClose( OurPipe );
END;
however, I'm getting an Accessviolation. unsure if I'm even going down the
right path.
Any other suggestions?
