Sorry my post was updated. Now, I use the GIO channel. But my problem was
the same:
.......
mkfifo("./fifo.sah", S_IRUSR);
fd=open("./fifo.sah", O_RDONLY);
channel=g_io_channel_unix_new(fd);
g_io_add_watch(channel,G_IO_IN,(GIOFunc) func2run, NULL); <- here the prog
wait and I must kill it
.......

It seems to me that I solve it replacing "S_IRUSR" by "S_IRUSR & S_IWUSR"
when I create the fifo...because now the prog run normally
......
mkfifo("./fifo.sah", S_IRUSR & S_IWUSR);
fd=open("./fifo.sah", O_RDONLY);
channel=g_io_channel_unix_new(fd);
g_io_add_watch(channel,G_IO_IN,(GIOFunc) func2run, NULL);
......

Now, I don't know how to use the fifo because when I try to write to
./fifo.sah, I get "permission denied"

Thanks in advance,
