$Log: lpvm.h,v $
 * Revision 1.9  1997/06/27  19:53:55  pvmsrc
 * Fixed polltype/polltime bug in AIX4MP.
 *
 * Revision 1.8  1997/06/27  17:32:22  pvmsrc
 * Updated for WIN32 header files & Authors.
 *
 * Revision 1.7  1997/05/07  21:23:28  pvmsrc
 * Added new pvmupkstralloc() for dynamic string unpacking lunacy.
 * 	- with proto in header.
 *
 * Revision 1.6  1997/03/17  20:56:34  pvmsrc
 * include sys/types.h for SUNOS in.h problem.
 *
 * Revision 1.5  1997/03/06  21:06:58  pvmsrc
 * 		define struct ttpcb and TT states
 * 		added includes for this struct defn
 *
 * Revision 1.4  1997/02/13  23:35:42  pvmsrc
 * Added new PvmNoReset setopt/getopt option.
 * 	- added new pvmnoreset, pvmnoresetindex globals in lpvm.[ch].
 * 	- to set use pvm_putinfo() -> PVMNORESETCLASS first avail w/lock,
 * 		save index in pvmnoresetindex.
 * 	- to unset use pvm_delinfo().
