anyway thanks to both of you for all the input will try it out now :-)
recv() returns the number of bytes actually read, the passed in buffer
only limits the upper bound of how much it will read. If 3 bytes are
what's available when you call recv(), it will return immediately
having given you those 3 bytes. It only blocks if no data is currently
available at all (and the socket isn't in non-blocking mode)
I'm unsure about this too can I write to the same socket id (from a
second
thread) while a recv is blocking? or do I have to create a second
socket? if
yes how?, can I clone it somehow?
Writing to the same socket from multiple threads is perfectly valid,
as with any other file descriptor.
