Int 2F/AX=112Eh

NETWORK REDIRECTOR (DOS 4.0+) - EXTENDED OPEN/CREATE FILE

AX = 112Eh
SS = DS = DOS DS
ES:DI -> uninitialized SFT for file.
STACK:
WORD file attribute for created/truncated file
low byte = file attributes
high byte = 00h normal create/open, 01h create new file.
SDA first filename pointer -> fully-qualified filename.
SDA extended file open action = action code
(see #01770 at INT 21/AX=6C00h).
SDA extended file open mode = open mode for file (see INT 21/AX=6C00h)

Return:
CF set on error
AX = error code
CF clear if successful
CX = result code
01h file opened
02h file created
03h file replaced (truncated)
SFT initialized (except handle count, which DOS manages itself)

Note: This function is called by the DOS 4.0+ kernel

BUG: This function is not called correctly under some DOS versions (at least 5.0 and 6.2): the file attribute on the stack is not correct if the action code is 11h, the result code in CX is not passed back to the application.
