1------------------------------------------------------------------------------ 2The adjtimed daemon emulates the BSD adjtime(2) system call. The 3adjtime() routine communicates with this daemon via SYSV messages. 4 5The emulation uses an undocumented kernel variable (as of 6.0/2.0 6and later releases) and as such it cannot be guaranteed to work in 7future HP-UX releases. Perhaps HP-UX will have a real adjtime(2) 8system call in the future. 9 10Author: Tai Jin (tai@sde.hp.com) 11------------------------------------------------------------------------------ 12 13IMPORTANT NOTE: This stuff must be compiled with no optimization !! 14 15NOTE: This code is known to work as of 8.0 on s300's, s700's and s800's. 16 PLEASE do not modify it unless you have access to kernel sources 17 and fully understand the implications of any changes you are making. 18 One person already has trashed adjtimed by making it do "the right 19 thing". This is not an exact replacement for BSD adjtime(2), don't 20 try to make it into one. 21 22 -- Ken 23
