Routine Description:
|
|
|
|
This routine parse an NCP response.
|
|
|
|
Packet types:
|
|
|
|
'G' Generic packet ( )
|
|
|
|
Field types, request/response:
|
|
|
|
'b' byte ( byte* )
|
|
'w' hi-lo word ( word* )
|
|
'x' ordered word ( word* )
|
|
'd' hi-lo dword ( dword* )
|
|
'e' ordered dword ( dword* )
|
|
'-' zero/skip byte ( void )
|
|
'=' zero/skip word ( void )
|
|
._. zero/skip string ( word )
|
|
'p' pstring ( char* )
|
|
'c' cstring ( char* )
|
|
'r' raw bytes ( byte*, word )
|
|
|
|
Added 3/29/95 by CoryWest:
|
|
|
|
'W' lo-hi word ( word / word*)
|
|
'D' lo-hi dword ( dword / dword*)
|
|
'S' unicode string copy as NDS_STRING (UNICODE_STRING *)
|
|
'T' terminal unicode string copy as NDS_STRING (UNICODE_STRING *)
|
|
|
|
't' terminal unicode string with the nds null copied
|
|
as NDS_STRING (UNICODE_STRING *) (for GetUseName)
|
|
|
|
Return Value:
|
|
|
