Hi,
I'm trying to use a g_spawn call to handle a pipe. I'm calling glib-genmarshal from my program, and I'd like to avoid having to create a marhallers.list file.
The command I'm trying to get to work is this:

Code: (C)
1	g_spawn_command_line_sync("echo VOID:INT,INT \| glib-genmarshal --stdinc --body", &output, NULL, NULL, &error);

but this results in output holding the command that was passed to g_spawn.
error is still NULL and the function returns TRUE (indicating success).
So my question is this: Does anyone know how to use a pipe with a g_spawn call (I can use g_spawn_sync if necessary, but I'd prefer to use g_spawn_command_line_sync).
Thank you...

Does output hold the string "echo VOID:INT,INT | glib-genmarshal --stdinc --body", then?

You could use g_spawn_async_with_pipes, g_spawn_command_line_sync seems to use it internally, anyway.

Is it?
g_spawn_command_line_sync("/bin/sh -c 'echo VOID:INT,INT | glib-genmarshal --stdinc --body'", &str, NULL, NULL ,NULL);
