Function Documentation

adjust_extension_z()

void __amandacall adjust_extension_z	(	char *	filename_in_z,
		char *	filename_out_z )

It will just add to the filename_out_z the extension of the filename_in_z, because some compression formats like lzma and brotli needs always the correct extension to extrac or list process

Parameters

filename_in_z	the input filename
filename_out_z	the output file that will have the extension adjusted

Returns

void

contains_dot_dot()

bool contains_dot_dot

(

char const *

name

)

Tar related function, version 1.34 Return nonzero if NAME contains ".." as a file name component.

createtempfilename_and_keep_z()

int createtempfilename_and_keep_z	(	char *	path1,
		char *	out_z,
		WCHAR *	signature_z )

It will just create a windows based temp file using the signature_z information

Parameters

path1	the path where it will create
out_z	the utf-8 encoded temp file
signature_z	the 3 characters to be used as the initial data on the destination temp file

Returns

0 on error, 1 otherwise

createtestfilename()

int createtestfilename

(

char *

path1

)

It will create a test filename on the given path and delete it just to see if it is writable

Parameters

path1

the folder where the file need to be created

Returns

0 on error, 1 otherwise

extract_archive()

void extract_archive

(

void

)

Tar related function, version 1.34 Extract a file from the archive.

get_extraction_progress_information_ar()

int __stdcall get_extraction_progress_information_ar	(	char *	warning_ar,
		char *	filename_ar,
		char *	folder_feline )

It will retrieve the extraction information for each call, see the sample project to see how to use it correctly

Parameters

warning_ar	the warning information if any
filename_ar	the filename that was just extracted
folder_feline	if it was a folder

Returns

always 0

is_compressed_z()

bool __amandacall is_compressed_z

(

char *

filename_in_z

)

It will read the extension to detect whether the file is a valid compressed file, wide path capable my ric...

Parameters

filename_in_z

the filename

Returns

0 if not compressed, 1 otherwise

is_encrypted_gnu_tar_arp()

bool is_encrypted_gnu_tar_arp

(

char *

file_arp_utf_8

)

Wide path capable, only for Tar files, it will check to see if in the file the information stored during the encryption is available, and if yes what is the encryption used, notice that for the moment the only software capable of using these encryption methods is the Parolin project, loading these encrypted files with tar.exe or Winrar or 7zip will only report an invalid Tar file

Parameters

file_arp_utf_8

the file to test, utf-8 based

Returns

false if not encrypted, true otherwise

ispathfile()

int ispathfile

(

char *

path

)

It will test the utf-8 encoded path to see if it do exist and is a file

Parameters

path	utf-8 encoded path to test

Returns

0 if the path is not a file or valid, 1 if it is a readable file

ispathfolder()

int ispathfolder

(

char *

path

)

To know whether the path is valid and a folder

Parameters

path	the path to test

Returns

0, if invalid or not a folder, 1 if it is a folder

ispathreadonly()

int ispathreadonly

(

char *

path

)

To know whether the path is read-only

Parameters

path	the path to test

Returns

1 if the path is read-only, -1 on error and 0 otherwise (if not read-only)

replace_extension_arp()

void __stdcall replace_extension_arp	(	char *	whole_path_arp,
		char *	new_extension_arp,
		char *	out_data_arp )

It will replace the extension with a new one provided

Parameters

whole_path_arp	the input path
new_extension_arp	the new extension
out_data_arp	the output file

ricardo_convert_m()

int __fastcall ricardo_convert_m	(	int	a_m,
		int	b_m,
		SYSTEMTIME *	smtime )

rspmakedir()

int rspmakedir

(

char *

path

)

Function to recursively create a path, it will try to create each subfolder since the first one and not only the last subfolder

Parameters

path	the path to create, cannot be relative (remember it)

Returns

0 if ok, an error otherwise

rspmakedir_v2()

int rspmakedir_v2

(

char *

path

)

Function to create the whole path, it will try to create each subfolder until the end recursively

Parameters

path	the path to create, cannot be relative (remember it)

Returns

0 if ok, an error otherwise

stripfilenameandpath()

int stripfilenameandpath	(	char *	path,
		char *	onlypath,
		char *	onlyfilename )

It will split the path in folder and file (Windows based), UNC capable too

Parameters

path	the input path
onlypath	only the path, can be NULL if not required
onlyfilename	only the filename, can be NULL if not required

Returns

always 0

stripfilenameandpath_amanda_s_smart_ape()

int __stdcall stripfilenameandpath_amanda_s_smart_ape	(	char *	path,
		char *	onlypath,
		char *	onlyfilename )

stripfilenameandpath_unix_arp()

int stripfilenameandpath_unix_arp	(	char *	path,
		char *	onlypath,
		char *	onlyfilename )

It will split the path in folder and file (Unix based)

Parameters

path	the input path
onlypath	only the path, can be NULL if not required
onlyfilename	only the filename, can be NULL if not required

Returns

always 0

strrstr()

char * strrstr	(	char *	s1,
		char *	s2 )

It will return the last occurrence of a string inside the string

Parameters
