AH = 41h DS:DX -> ASCIZ filename (no wildcards, but see notes) CL = attribute mask for deletion (server call only, see notes)
Return:
CF clear if successful AX destroyed (DOS 3.3) AL seems to be drive of deleted file CF set on error AX = error code (02h,03h,05h) (see #01680 at AH=59h/BX=0000h)
Notes: (DOS 3.1+) wildcards are allowed if invoked via AX=5D00h, in which case the filespec must be canonical (as returned by AH=60h), and only files matching the attribute mask in CL are deleted. DR DOS 5.0-6.0 returns error code 03h if invoked via AX=5D00h; DR DOS 3.41 crashes if called via AX=5D00h with wildcards. DOS does not erase the file's data; it merely becomes inaccessible because the FAT chain for the file is cleared. Deleting a file which is currently open may lead to filesystem corruption. Unless SHARE is loaded, DOS does not close the handles referencing the deleted file, thus allowing writes to a nonexistant file.. Under DR DOS and DR Multiuser DOS, this function will fail if the file is currently open. Under the FlashTek X-32 DOS extender, the pointer is in DS:EDX
BUG: DR DOS 3.41 crashes if called via AX=5D00h
