NAME
Ns_Gzip, Ns_SetGzipProc - GZIP compression supportSYNOPSIS
#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 );
