83Plus:Software:usb8x/Asm Interface/MSD/DOS renameFileEntry

Synopsis

Name: DOS_renameFileEntry

Minimum usb8x version: 0.10

Renames a file or folder.

Inputs

• HL points to an ASCIIZ string of the old file/directory name, including path (ex. "/test1/test2/RenameMe.txt")
• DE points to an ASCIIZ string of the new name (ex. "NewName.txt")

Outputs

• Entry is renamed
• C set if problems

Destroys

• AF, BC, DE, HL

Notes

This works with both file and folder names. Example code to rename "old.txt" to "new.txt" in the root directory:

ld hl,sOldName
ld de,sNewName
U_CALL DOS_renameFileEntry
...
sOldName: DB "/old.txt",0
sNewName: DB "/new.txt",0

If you are writing an application, you must copy the strings you use to RAM first, or else usb8x will not be able to see them.
