Имена файлов

воть хедеры для длинных имён файлов...

ф-ция DeleteFile и соотвецтвенно XDelete работают не корректно...

помогите разшифровать в структуре LFN даты

и подкорректируйте вышеуказаные функции плз если можете...

и ещё у мня есть архив THelp - хелп по функциям прерывания... модеры если нужно, отпишитесь сюда или на мыло.

А по поводу XDelete можно заюзать эту же функцию, добавив параметр 'атрибут'.

PS: Interrupt 21h Function 7141h
Deletes the given file or files. If the specified filename contains a wildcard character, this function can delete multiple files that match the wildcard.

mov ch, MustMatchAttrs ; see below
mov cl, SearchAttrs ; see below
mov dx, seg Filename ; see below
mov ds, dx
mov dx, offset Filename
mov si, WildcardAndAttrs ; see below

Parameters

MustMatchAttrs

Additional filter on the attributes specified in SearchAttrs. This parameter can be a combination of these values:

_A_NORMAL (0000h)
The file can be read from or written to. This value is valid only if used alone.
_A_RDONLY (0001h)
The file can be read from, but not written to.
_A_HIDDEN (0002h)
The file is hidden and does not appear in an ordinary directory listing.
_A_SYSTEM (0004h)
The file is part of the operating system or is used exclusively by it.
_A_VOLID (0008h)
The name specified by Filename is used as the volume label for the current medium.
_A_SUBDIR (0010h)
The name specified by Filename is used as a directory, not a file.
_A_ARCH (0020h)
The file is an archive file. Applications use this value to mark files for backup or removal.


SearchAttrs

File attributes to search for. This parameter can be a combination of these values:

_A_NORMAL (0000h)
_A_RDONLY (0001h)
_A_HIDDEN (0002h)
_A_SYSTEM (0004h)
_A_VOLID (0008h)
_A_SUBDIR (0010h)
_A_ARCH (0020h)


Filename

Address of a null-terminated string specifying the name of the file to delete. If WildcardAndAttrs is 1, the "*" and "?" wildcard characters are permitted in the filename. Long filenames are allowed.

WildcardAndAttrs

Search criteria. This parameter must be one of these values:

0 Wildcard characters are not allowed in Filename. Any specified attributes are ignored.
1 Wildcard characters are allowed in Filename. Files with specified attributes are matched.


Return Value

Clears the carry flag if successful. Otherwise, the function sets the carry flag and sets the AX register to an error value.

Remarks

Wildcard searches are more flexible in Windows 95 than in MS-DOS. Both long filenames and aliases are considered in searches. For example, *1 finds Windows 95 filenames (both long filenames and aliases) that end in a 1 and *mid* finds filenames that contain the characters mid. In MS-DOS and in Windows 95 searching on real-mode FAT directories, all characters after the first * are ignored.
For more information about how MustMatchAttrs and SearchAttrs are used, see the comments for Find First File (Interrupt 21h Function 714Eh).

Find First File and subsequent calls to Find Next File (Interrupt 21h Function 714Fh) use the following algorithm to match the attributes of a file or directory (referred to as Attributes in the algorithm) against MustMatchAttrs and SearchAttrs.

if ((((<MustMatchAttrs> & ~<Attributes>) & 0x3F) == 0)
&& (((~<SearchAttrs> & <Attributes>) & 0x1E) == 0))
{
return the file or directory name
}
else
{
continue searching for the next name
}


The following table lists the MustMatchAttrs and SearchAttrs values for some common searches where the specified filename is "*.*". In the table, the word normal means that the read only, hidden, or system attributes have not been set. Parentheses are used to indicate that a file or directory has more than one attribute. For example, (hidden and system) indicates that a file or directory has both the hidden attribute and the system attribute.

MustMatchAttrs SearchAttrs Find results
10h 10h All normal directories
10h 12h All normal and hidden directories
10h 14h All normal and system directories
10h 16h All normal, hidden, system and (hidden and system) directories

По поводу дат:
Юзай 'Interrupt 21h Function 71A6h', предварительно открыв файл спомощью 'Interrupt 21h Function 716Ch' с режимом доступа OPEN_ACCESS_RO_NOMODLASTACCESS (0004h) и 'Interrupt 21h Function 71A7h Minor Code 0h', 'Interrupt 21h Function 71A7h Minor Code 1h' соответственно.

хм по атрибутам это хорошо, но XDelete это рекурсивное удаление вложеных файлов и папок..

хотя коечё всётаки придумал пасиб за помощ...:)
