How can we get to know data on socket?

Santoshkb · 10-05-2007, 09:43 AM

client wants to recv(read) data, when server sends,

I cant use while (1) (recv()!= -1) as client also handles task of sending data.continuously,
i.e sending is constant, but when data is available, want to read, and take action,

awaiting for your valuable suggestion.

thanks

There are a few different ways of doing this.

1) Have 2 threads. 1 for reading, and 1 for writing. Most clean

2) Use non-blocking sockets, check return codes from recv to determine if data was read. Psuedo messy

3) Use select() to check for data availability. Sortof messy, but can be clean.

Those are the best options I can come up with.
