Getting TCP Port status through C API
Does anyone know if there is a C API call to get the status of a TCP port? As opposed to running netstat and parsing the results. At the moment I have to attempt to bind() and pick up on the address in use error which isn't very elegant

Thanks

This is on Solaris 10. Unfortunately not Linux where I could have used the proc filesystem

NAME

     setfib -- execute a utility with an altered default network view

SYNOPSIS

     setfib [-F] fib utility [argument ...]

DESCRIPTION

     The setfib utility runs another utility with a different routing table.  The table number fib will be used by default for all sockets started

ENVIRONMENT

     The PATH environment variable is used to locate the requested utility if the name contains no '/' characters.

EXIT STATUS

     If utility is invoked, the exit status of setfib is the exit status of utility.

     An exit status of 126 indicates utility was found, but could not be executed.  An exit status of 127 indicates utility could not be found.

EXAMPLES

     Run netstat(1) to view the second routing table.

	   setfib -F 1 netstat -rn
     or
	   setfib 1 netstat -rn
     or
	   setfib -1 netstat -rn
