NAME
       Ns_Gzip, Ns_SetGzipProc - GZIP compression support

SYNOPSIS
       #include "ns.h"

       int
       Ns_Gzip(buf, len, level, dsPtr)

       void
       Ns_SetGzipProc(proc)

ARGUMENTS
       Tcl_DString   dsPtr   (out)     Output buffer to placed compressed string.

       int	     len     (in)      Length of string pointed to by buf.

       char	     *buf    (in)      Pointer to string to compress.

       int	     level   (in)      Requested GZIP compression level.

       Ns_GzipProc   proc    (in)      Procedure to GZIP content.

DESCRIPTION
       These functions enable GZIP compress of text buffers.

       int Ns_Gzip(buf, len, level, dsPtr)
	      This  function compresses a string pointed to by buf of length len, appending the output to the given dsPtr.  The output buffer must
	      already be initialized.  The level parameter specifies the compress level between 0 and 9; see the documentation in the  zlib.h  for
	      details.

	      The function will return NS_OK if compression was successful, otherwise NS_ERROR.  A call to Ns_SetGzipProc to install a compression
	      function must have already occured.  The nszlib module will install a suitable function when loaded.

       void Ns_SetGzipProc(proc)
	      This function is used to install a compression function for Ns_Gzip.  A call to Ns_SetGzipProc would normally be in the  module-load
	      routine of a module which provides compression support, e.g., the nszlib module.	The function should match the type Ns_GzipProc:

	      typedef int Ns_GzipProc(
		char *buf, int len, int level, Tcl_DString *dsPtr
	      );
