AX = 4302h DS:DX -> ASCIZ pathname
Return:
CF clear if successful CX = access rights (see #01421) AX = CX (DR DOS 5.0) CF set on error AX = error code
Desc: Determine which operations the calling program may perform on a specified file without being required to provide a password.
Notes: This protection scheme has been coordinated on all current Digital Research/Novell operating systems (DR DOS 3.41+, DRMDOS 5.x, and FlexOS 2+). This function is documented in DR DOS 6.0 and corresponds to the "Get/Set File Attributes" function, subfunction 2, documented in Concurrent DOS.. Only FlexOS actually uses the "execution" bits; DR DOS 3.41+ treats them as "read" bits.. DR DOS 3.41-5.x only use bits 0-3. Only DR DOS 6.0 using a DRMDOS 5.x security system allowing for users and groups uses bits 4-11.
