* HISTORY
* $Log: socket.h,v $
* Revision 2.5 89/03/09 22:07:36 rpd
* More cleanup.
*
* Revision 2.4 89/02/25 17:56:16 gm0w
* Made CMUCS branches always true, made MACH_VMTP
* and VICE conditional defines unconditional.
* [89/02/14 mrt]
*
* Revision 2.3 88/08/24 02:44:39 mwyoung
* Adjusted include file references.
* [88/08/17 02:23:09 mwyoung]
*
* 09-Apr-88 Mike Accetta (mja) at Carnegie-Mellon University
* Added SO_USEPRIV definition (based on ECE implementation);
* CS_SOCKET => CMUCS.
* [ V5.1(XF23) ]
*
* 06-Jan-88 Jay Kistler (jjk) at Carnegie Mellon University
* Made file reentrant. Added declarations for __STDC__.
*
* 1-Jul-87 Daniel Julin (dpj) at Carnegie-Mellon University
* Updated from new VMTP sources from Stanford (June 87).
*
* 28-May-87 Daniel Julin (dpj) at Carnegie-Mellon University
* Added VMTP.
*
* 7-Feb-87 Avadis Tevanian (avie) at Carnegie-Mellon University
* Merge VICE changes -- include vice.h and change to #if VICE.
*
* 2-Dec-86 Jay Kistler (jjk) at Carnegie-Mellon University
* VICE: added SO_GREEDY option.
*
* 25-Jan-86 Avadis Tevanian (avie) at Carnegie-Mellon University
* Upgraded to 4.3.
*
* 16-Oct-85 Mike Accetta (mja) at Carnegie-Mellon University
* CMUCS: added SO_CANTSIG definition.
* [V1(1)]
