spawning a command like this: zip -z foo < foowhat with...

[Giuseppe Torelli-2]

Hi,

I apologize for asking a gtk related question into xfce4 ml.
I need to spawn the program in the object with g_spawn_async_with_pipes
or other kind of. The problem is that I don't get any error message but
the command is simply not executed. Is it possible to use the < redirector
with glib?

Thank you,

I'm pretty sure that that won't work, because redirection is a shell feature.

Maybe you can use g_spawn_command_line_sync to execute that command

Unfortunately it doesn't work. Any other idea?

I come here a bit in a hurry, so I just throw my random guess: fork
before running the command.  I think this should do it.

Sort of...

use: g_spawn_async_with_pipes (zip -z foo)

and write foowhat to the input_pipe...

Then it works.
