Mon Feb 8 10:05:00 1999 Richard Frith-Macdonald <richard@brainstorm.co.uk>
|
||||
|
||||
* Source/include/NSByteOrder.h: Implemented a full set of byte-swapping
|
||||
inline functions for integers with known sizes.
|
||||
* Source/NSData.m: Corrected serialization/deserialization routines to
|
||||
do byte-swapping using new functions.
|
||||
* Source/UnixFileHandle.m: Use new byte-swapping functions rather than
|
||||
htonl(), htons(), ntohl(), ntohs().
|
||||
* Source/NSUnarchiver.m: Use new byte-swapping functions.
|
||||
|
||||
1999-02-04 Adam Fedor <fedor@gnu.org>
|
||||
|
||||
* config/config.printf.c: New file.
