Parameters:
* eax = 58 - function number
* ebx = pointer to the information structure
Format of the information structure:
* +0: dword: 4 = subfunction number
* +4: dword: ignored
* +8: dword: ignored
* +12 = +0xC: dword: ignored
* +16 = +0x10: dword: pointer to buffer for system operations
(4096 bytes)
* +20 = +0x14: ASCIIZ-name of file, the rules of names forming are
given in the general description
Returned value:
* eax = 0 - success, otherwise file system error code
* ebx destroyed
Remarks:
* Ramdisk and floppies do not support this function, it is only
for hard disks.
======================================================================
======== Function 58, subfunction 5 - rename/move file/folder. =======
======================================================================
Parameters:
* eax = 58 - function number
* ebx = pointer to the information structure
Format of the information structure:
* +0: dword: 5 = subfunction number
* +4: dword: ignored
* +8: dword: ignored
* +12 = +0xC: dword: ignored
* +16 = +0x10: dword: pointer to buffer for system operations
(4096 bytes)
* +20 = +0x14: ASCIIZ-name of file, the rules of names forming are
given in the general description
* +20+n: (at once after terminating null character) new
ASCIIZ-name, must start from /hd/1, that is interpreted as
the hard disk, indicated in the first name
(moving from one disk to another is not supported)
Returned value:
* eax = 0 - success, otherwise file system error code
* ebx destroyed
Remarks:
* Ramdisk and floppies do not support this function, it is only
for hard disks.
* If the new ASCIIZ-name is strongly incorrect, i.e. does not start
from /hd/1, /hd/first, /harddisk/1, /harddisk/first or after this
space or null character follows, function returns, strangely
enough, error code 4. It is the only function which returns
this code.
