Dov Harel (DovH) 21-Apr-1992
|
|
|
|
Environment:
|
|
|
|
This code should execute in all environments supported by RPC
|
|
(DOS, Win 3.X, and Win/NT as well as OS2).
|
|
|
|
Comments:
|
|
|
|
Split charconv.cxx into
|
|
|
|
charconv.cxx - Character related conversion.
|
|
intconv.cxx - Integral type conversion.
|
|
dataconv.cxx - Interpretation style converstion.
|
|
|
|
Revision history:
|
|
|
|
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

o Aligns the buffer pointer to the next (0 mod 8) boundary,
