Hello all,
I'm using the following code fragment
ok = g_spawn_async_with_pipes("/tmp", argv, NULL,
G_SPAWN_SEARCH_PATH,
NULL, NULL, NULL,
&std_in, &std_out, &std_err,
NULL);
channel_out = g_io_channel_unix_new(std_in);
channel_in = g_io_channel_unix_new(std_out);
channel_err = g_io_channel_unix_new(std_err);
g_io_channel_set_close_on_unref (channel_in, TRUE);
g_io_channel_set_close_on_unref (channel_err, TRUE);
g_io_add_watch(channel_in,G_IO_IN , thread_reader,NULL);
g_io_add_watch(channel_err, G_IO_ERR , thread_reader,NULL);
And this is the callback.
gboolean thread_reader(GIOChannel *source, GIOCondition condition,
gpointer data) {
GString *_output;
GIOStatus status;
output = g_string_new("");
status = g_io_channel_read_line_string(source,output,NULL,NULL);
if (status == G_IO_STATUS_EOF) {
g_io_channel_close(source);
g_io_channel_unref(source);
return FALSE;
}
}
It all works and my thread_reader is being called properly, but when I
do this the performance of the GUI is aweful, can't resize the window,
etc.... The second I kill the spawned app the performance returns back
to normal. Is there anything I can to to make this work better. My app
that I am spawning is very chatty, and so there is a lot of output being
processed, so I don't think it is hanging on the read_line.
TIA,
Kevin
