Re: g_io_add_watch, g_io_channel_read stops working after sometime.
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.

g_io_add_watch, g_io_channel_read stops working after sometime.
Hi, I am trying to write a program based on client-server architecture. I need only one client connection hence i am first listening to client then accept() is called. after accept() i call g_io_channel_unix_new () and then g_io_add_watch() and later in the function i use g_io_channel_read to read data from the channel. Everything works fine till 4-5 requests from the client. Later the server simply stops listening to client. I have tried tcpdump on server side and i do recieve the TCP packet from the client.
