ns_gzip
Ns_Gzip(3aolserver) AOLserver Library Procedures Ns_Gzip(3aolserver)
__________________________________________________________________________________________________________________________________________________
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
);
