Expert Query on timing, threads, networking plz.... :S

network efficiently without hogging the network. Is the most efficient
way just converting double[n][4] into a string? First send the value of n, then send each double value in a
loop.Receiving side, n will determine the no of double values to
recieve.Maybe thread the network transfer so that the frequency
of "cpu collecting" remains precisely every second? You may consider a list of data sharing between both thread and access
should be syncronized between them.
data collecting thread will collect data and add this to rear of list
and other thread will take the as much as data availabel in list and
will copy it and send it to network.2. How does one create/use threads in C, AND C++? Do threads differ in

Two quick queries:

Now, I want to transfer this data set (double procValues[n][4]) over a
TCP or UDP network connection to a local host for graphing and storing
in a database tool.

I've read Beej's Networking Guide
http://www.ecst.csuchico.edu/~beej/guide/net/ and going to follow his
code.

However I don't know how am going to send a double[n][4] over the
network efficiently without hogging the network. Is the most efficient
way just converting double[n][4] into a string?

If you plan on using send and recv (as is suggested by the link), you
have no option besides converting the 2D array into a string (for send)
and reading the character stream (from recv) to retrieve the double
values. NB: Neither send nor recv belong to the standard libraries of
C and C++.
