socket problems with cc compile options???

Hi there, a newbie as far as compiling c.
I have a problem, I've ported a fairly simple perl socket program over to c.

I compiled it as follows

cc simplesocket.c -lsocket -lnsl

compiles great, no errors.

When I launch it from the command line, it works great!!!!

However, if I launch this program from within another socket program
( a perl socket server (listener) program, basically doing an exec of this compiled program ).
The server program has no problems launching any other kinds of socket apps.

Is there some option I need to tell the compiler that will tell the program it will be running beneath another socket program????

Once again a newbie, any help appreciated.

socket_set_block - Sets blocking mode on a socket resource

SYNOPSIS
bool socket_set_block (resource $socket) DESCRIPTION
The socket_set_block(3) function removes the O_NONBLOCK flag on the socket specified by the $socket parameter. When an operation (e.g. receive, send, connect, accept, ...) is performed on a blocking socket, the script will pause its execution until it receives a signal or it can perform the operation. PARAMETERS
o $socket - A valid socket resource created with socket_create(3) or socket_accept(3). RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 socket_set_block(3) example <?php $socket = socket_create_listen(1223); socket_set_block($socket); socket_accept($socket); ?> This example creates a listening socket on all interfaces on port 1223 and sets the socket to O_BLOCK mode. socket_accept(3) will hang until there is a connection to accept.
