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

unsquashfs
UNSQUASHFS(1) uncompress squashfs filesystems UNSQUASHFS(1)
NAME
mksquashfs - tool to uncompress squashfs filesystems
SYNOPSIS
unsquashfs [OPTIONS] FILESYSTEM [directories or files to extract]
DESCRIPTION
Squashfs is a highly compressed read-only filesystem for Linux. It uses zlib compression to compress both files, inodes and directories.
Inodes in the system are very small and all blocks are packed to minimize data overhead. Block sizes greater than 4K are supported up to a
maximum of 64K.
Squashfs is intended for general read-only filesystem use, for archival use (i.e. in cases where a .tar.gz file may be used), and in con-
strained block device/memory systems (e.g. embedded systems) where low overhead is needed.
OPTIONS
-v, -version
print version, licence and copyright information.
-d PATHNAME, -dest PATHNAME
unsquash to PATHNAME, default "squashfs-root".
-n, -no-progress
don't display the progress bar.
-no, -no-xattrs
don't extract xattrs in file system.
-x, -xattrs
extract xattrs in file system (default).
-p NUMBER, -processors NUMBER
use NUMBER processors. By default will use number of processors available.
-i, -info
print files as they are unsquashed.
-li, -linfo
print files as they are unsquashed with file attributes (like ls -l output).
-l, -ls
list filesystem, but don't unsquash.
-ll, -lls
list filesystem with file attributes (like ls -l output), but don't unsquash.
-f, -force
if file already exists then overwrite.
-s, -stat
display filesystem superblock information.
-e EXTRACT_FILE, -ef EXTRACT_FILE
list of directories or files to extract. One per line.
-da SIZE, -data-queue SIZE
Set data queue to SIZE Mbytes. Default 256 Mbytes.
-fr SIZE, -frag-queue SIZE
Set fragment queue to SIZE Mbytes. Default 256 Mbytes.
-r, -regex
treat extract names as POSIX regular expressions rather than use the default shell wildcard expansion (globbing).
Decompressors available
gzip
lzo
xz
