Environment:
|
|
|
|
This code should execute in all environments supported by RPC
|
|
(DOS, Win 3.X, and Win/NT as well as OS2).
|
|
|
|
Comments:
|
|
|
|
The EBCDIC to ASCII data conversion will not be tested until we
|
|
interoperate with some system which speaks EBCDIC.

Revision history:

|
|
... (long...)
|
|
|
|
Dov Harel 04-24-1992 Added char_array_from_ndr.
|
|
Dov Harel 04-24-1992 Fixed both _from_ndr to do EBCDIC => ASCII
|
|
conversion. Changed the ebcdic_to_ascii
|
|
table to "unsigned char" array type.
|
|
Donna Liu 07-23-1992 Added LowerIndex parameter to
|
|
<basetype>_array_from_ndr routines
|
|
Dov Harel 08-19-1992 Added RpcpMemoryCopy ([_f]memcpy)
|
|
to ..._array_from_ndr routines
