|
|
Abstract:
|
|
|
|
This module consists of the routine RxpSetField and its helpers
|
|
(RxpIsFieldSettable and RxpFieldSize).

|
|
|
|
Environment:
|
|
|
|
Portable to any flat, 32-bit environment. (Uses Win32 typedefs.)
|
|
Requires ANSI C extensions: slash-slash comments, long external names.

Revision History:
|
|
|
|
29-May-1991 JohnRo
|
|
Created.
|
|
06-Jun-1991 JohnRo
|
|
Fixed bug handling buffer size (it shouldn't be sent).
|
|
Fixed off-by-one error in string size handling in RxpFieldSize.
|
|
Added debug output.
|
|
12-Jul-1991 JohnRo
|
|
Added more parameters to RxpSetField(), to support RxPrintJobSetInfo().
|
|
Still more debug output.
|
|
17-Jul-1991 JohnRo
|
|
Extracted RxpDebug.h from Rxp.h.
|
|
01-Oct-1991 JohnRo
|
|
More work toward UNICODE.
|
|
21-Nov-1991 JohnRo
|
|
Removed NT dependencies to reduce recompiles.
|
|
31-Mar-1992 JohnRo
|
|
Prevent too large size requests.
