ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.9 is a general purpose data compression library.  All the code is
thread safe.  The data format used by the zlib library is described by RFCs
(Request for Comments) 1950 to 1952 in the files
http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
rfc1952 (gzip format).

All functions of the compression library are documented in the file zlib.h
(volunteer to write man pages welcome, contact [email protected]).  A usage example
................................................................................

PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.

Mark Nelson <[email protected]> wrote an article about zlib for the Jan.  1997
issue of Dr.  Dobb's Journal; a copy of the article is available at
http://marknelson.us/1997/01/01/zlib-engine/ .

The changes made in version 1.2.9 are documented in the file ChangeLog.

Unsupported third party contributions are provided in directory contrib/ .

zlib is available in Java using the java.util.zip package, documented at
http://java.sun.com/developer/technicalArticles/Programming/compression/ .

A Perl interface to zlib written by Paul Marquess <[email protected]> is available
................................................................................
  The deflate format used by zlib was defined by Phil Katz.  The deflate and
  zlib specifications were written by L.  Peter Deutsch.  Thanks to all the
  people who reported problems and suggested various improvements in zlib; they
  are too numerous to cite here.

    The 'zlib' compression library provides in-memory compression and

................................................................................


/*
ZEXTERN int ZEXPORT inflateInit OF((z_streamp strm));

     Initializes the internal stream state for decompression.  The fields
   next_in, avail_in, zalloc, zfree and opaque must be initialized before by
   the caller.  In the current version of inflate, the provide input is not
   read or consumed.  Any memory allocation will be deferred to the first call

   of inflate.  If zalloc and zfree are set to Z_NULL, inflateInit updates them
   to use default allocation functions.

     inflateInit returns Z_OK if success, Z_MEM_ERROR if there was not enough
   memory, Z_VERSION_ERROR if the zlib library version is incompatible with the
   version assumed by the caller, or Z_STREAM_ERROR if the parameters are
   invalid, such as a null pointer to the structure.  msg is set to null if
   there is no error message.  inflateInit does not perform any decompression.
   Actual decompression will be done by inflate().  So next_in, and avail_in,
................................................................................
  forced to flush.

  The detailed semantics are as follows.  inflate performs one or both of the
  following actions:

  - Decompress more input starting at next_in and update next_in and avail_in
    accordingly.  If not all input can be processed (because there is not
    enough room in the output buffer), then next_in and avail_on are updated
    accordingly, and processing will resume at this point for the next call of
    inflate().

  - Generate more output starting at next_out and update next_out and avail_out
    accordingly.  inflate() provides as much output as possible, until there is
    no more input data or no more space in the output buffer (see below about
    the flush parameter).
................................................................................
ZEXTERN int ZEXPORT compress OF((Bytef *dest,   uLongf *destLen,
                                 const Bytef *source, uLong sourceLen));
/*
     Compresses the source buffer into the destination buffer.  sourceLen is
   the byte length of the source buffer.  Upon entry, destLen is the total size
   of the destination buffer, which must be at least the value returned by
   compressBound(sourceLen).  Upon exit, destLen is the actual size of the
   compressed buffer.  compress() is equivalent to compress2() with a level
   parameter of Z_DEFAULT_COMPRESSION.

     compress returns Z_OK if success, Z_MEM_ERROR if there was not
   enough memory, Z_BUF_ERROR if there was not enough room in the output
   buffer.

.SH ARGUMENTS
.AS Tcl_TcpAcceptProc clientData
.AP Tcl_Interp *interp in
Tcl interpreter to use for error reporting.  If non-NULL and an
error occurs, an error message is left in the interpreter's result.
.AP int port in
A port number to connect to as a client or to listen on as a server.



.AP "const char" *host in
A string specifying a host name or address for the remote end of the connection.
.AP int myport in
A port number for the client's end of the socket.  If 0, a port number
is allocated at random.
.AP "const char" *myaddr in
A string specifying the host name or address for network interface to use
for the local end of the connection.  If NULL, a default interface is
chosen.

.SH SYNOPSIS
.nf
\fB#include <tcl.h> \fR

.SH ARGUMENTS
.AS Tcl_TcpAcceptProc clientData
.AP Tcl_Interp *interp in
Tcl interpreter to use for error reporting.  If non-NULL and an
error occurs, an error message is left in the interpreter's result.
.AP int port in
A port number to connect to as a client or to listen on as a server.
.AP "const char" *service in
A string specifying the port number to connect to as a client or to listen on as
 a server.
.AP "const char" *host in
A string specifying a host name or address for the remote end of the connection.
.AP int myport in
A port number for the client's end of the socket.  If 0, a port number
is allocated at random.
.AP "const char" *myaddr in
A string specifying the host name or address for network interface to use
for the local end of the connection.  If NULL, a default interface is
chosen.
.AP int async in
If nonzero, the client socket is connected asynchronously to the server.
.AP "unsigned int" flags in
ORed combination of \fBTCL_TCPSERVER\fR flags that specify additional
informations about the socket being created.
.AP ClientData sock in
Platform-specific handle for client TCP socket.
.AP Tcl_TcpAcceptProc *proc in
Pointer to a procedure to invoke each time a new connection is
accepted via the socket.
.AP ClientData clientData in
Arbitrary one-word value to pass to \fIproc\fR.
................................................................................
a remote client is pending.
.PP
The newly created channel is not registered in the supplied interpreter; to
register it, use \fBTcl_RegisterChannel\fR.
If one of the standard channels, \fBstdin\fR, \fBstdout\fR or \fBstderr\fR was
previously closed, the act of creating the new channel also assigns it as a
replacement for the standard channel.
.SS TCL_OPENTCPSERVEREX
.PP
\fBTcl_OpenTcpServerEx\fR behaviour is identical to \fBTcl_OpenTcpServer\fR but
gives more flexibility to the user by providing a mean to further customize some
aspects of the socket via the \fIflags\fR parameter.
.SH "PLATFORM ISSUES"
.PP
On Unix platforms, the socket handle is a Unix file descriptor as
returned by the \fBsocket\fR system call.  On the Windows platform, the
socket handle is a \fBSOCKET\fR as defined in the WinSock API.

server-side network interface to use for the connection.  This option
may be useful if the server machine has multiple network interfaces.
If the option is omitted then the server socket is bound to the
wildcard address so that it can accept connections from any
interface. If \fIaddr\fR is a domain name that resolves to multiple IP
addresses that are available on the local machine, the socket will
listen on all of them.










.PP
Server channels cannot be used for input or output; their sole use is to
accept new client connections. The channels created for each incoming
client connection are opened for input and output. Closing the server
channel shuts down the server so that no new connections will be
accepted;  however, existing connections will be unaffected.
