Int 61 Fn 000F  - Banyan Vines - Get Process Handle                        [N]

   AX = 000Fh subfn 0008h
   CX:BX -> request block (see #3121)
   DX = application's data segment (should be = CX)
   ES = DS

Return: AX = status
       0000h successful
       00A5h resource not available
Desc:  Returns a process handle to be used in other request blocks

Notes: This function is a prerequisite to all AX=000Fh subfunctions which
     expect a process handle in the request block
   Although subsequent calls from the same application return different
     process handles, there seem to be no restrictions on how many times
     an application may call this function (in fact, the code in the VINES
     toolkit library always calls it before issueing other AX=000Fh calls)

Format of request block:
Offset Size    Description (Table 3121)
 00h   WORD    0008h
 02h   WORD    magic number (FEFEh)
 04h   WORD    buffer for return code (set to 0 before calling)
 06h   WORD    reserved
 08h   WORD    reserved (obviously not used; set to 0 before calling)
 0Ah   DWORD   process type (1 = transient, 2 = resident; destroyed on exit)
 0Eh   WORD    buffer for process handle
