Module Name:
charconv.cxx
Abstract:
Single byte character conversion routines.
Author:
Donna Liu (DonnaLi) ??-???-19??
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

Routine Description:
Unmarshall a single char from an RPC message buffer into
the target (*Target). This routine:
o Unmarshalls the char (as unsigned char); performs data
conversion if necessary, and
o Advances the buffer pointer to the address immediately
following the unmarshalled char.
Arguments:
SourceMessage - A pointer to an RPC_MESSAGE.
IN - SourceMessage->Buffer points to the address just prior to
the char to be unmarshalled.
OUT - SourceMessage->Buffer points to the address just following
the char which was just unmarshalled.
Target - A pointer to the char to unmarshall the data into.
Return Values:
None.

the last char which was just unmarshalled.
LowerIndex - Lower index into the target array.
