Function Documentation

Cancel_xz__9()

int __stdcall Cancel_xz__9

(

void

)

to cancel the execution

Returns

int 0

Compress_xz__9()

int __stdcall Compress_xz__9	(	char *	infile__aakp,
		char *	outfile_rspk,
		int	level_juliete,
		int	threads_____z )

to compress a file using standard xz compression

Parameters

infile__aakp	the utf-8 encoded uncompressed file
outfile_rspk	the utf-8 encoded resulting file
level_juliete	the compression level, range from 0 to 9
threads_____z	the number of threads, until version 0.8.4 it need to be 1, due to some problems in the internals of xz lib, as you will see if more than one thread is used it will slow down the execution rather than speeding up (notice that compression level in multi-thread mode is controled internally)

Returns

int
0 - No error
1 - Cannot open input file
2 - Cannot open output file
3 - Error in the initialization of compression
119 - User cancel

interface1_9()

int __stdcall interface1_9	(	__INT32_OR_INT64	argumento1,
		__INT32_OR_INT64	argumento2,
		__INT32_OR_INT64	argumento3,
		__INT32_OR_INT64	argumento4 )

Pause_xz__9()

int __stdcall Pause_xz__9

(

void

)

to pause the execution

Returns

int 0

pedro_dprintf()

void pedro_dprintf	(	int	amanda_level,
		char *	format,
			... )

pedro_dprintf2()

void pedro_dprintf2	(	int	amanda_level,
		char *	format,
			... )

pedro_dprintf2 is my variant of my debug function because too much calls to pedro_dprintf these days, I am lazy, sorry....

em brotli or brotli2

Parameters

amanda_level	if equal or above 0 print the string
format	printf based format
...

Progress_xz__9()

int __stdcall Progress_xz__9

(

void

)

To get the progress value.

Returns

int it range from 0 to 10000

Resume_xz__9()

int __stdcall Resume_xz__9

(

void

)

to resume the execution

Returns

int 0

Returnvalue()

int __stdcall Returnvalue

(

)

to get the last error value, must be 0 if ok

Returns

int the return value, 0 if no error

Running()

int __stdcall Running

(

)

to see whether it is running

Returns

int 0 if idle or 1 if running

Uncompress_xz__9()

int __stdcall Uncompress_xz__9	(	char *	infile__aakp,
		char *	outfile_rspk )

Function to uncompress a default xz compressed file.

Parameters

infile__aakp	utf-8 encoded compressed xz file
outfile_rspk	utf-8 encoded destination uncompressed file

Returns

int
0 - No error
1 - Cannot open input file
2 - Cannot open output file
119 - User cancel

xz_compress()

int xz_compress	(	char *	inputfile,
		char *	outputfile,
		int	level )

function to compress files in the standard .xz format the level range from 0 to 9, 9 to best compression

xz files can be decompressed with Winrar

if threads is used the compression level is the default or controled internally, level don't matter (26/sep/2021, 02:45)

xz_uncompress()

int xz_uncompress	(	char *	inputfile,
		char *	outputfile )

internal function to decompress xz file

Parameters

inputfile
outputfile

Returns

int
