Re: Memory allocation

Grrr.... what difference does it make how big the system's buffer is??

recv() doesn't wait for the buffer to be full before reading the data into
your program!  It just gives you whatever happens to be in the buffer so 
far.

If you want to read in fixed-size buffers use the routine that I ALREADY
POSTED in my last message to you.   It will force the data to be received
in fixed size chunks.

If you REALLY want to know how big the buffer is, and/or you REALLY want
to change the buffer size, you can use the setsockopt/getsockopt APIs to
do that...  but I really don't recommend it.   Just use that routine
that I posted -- that's why I took the time to write it!!
