Re: g_io_add_watch, g_io_channel_read stops working after sometime.

[Rehan <rehan shaikh radarspot com>]

Hi James,

     The problems seems to be solved.. I had to return TRUE from my callback
function read_request() and listentosocket is the channel. "listentosocket =
g_io_channel_unix_new (global_sock);"

thanks for your reply and yes i am now listening to G_IO_HUP also...

regards,
Rehan.
