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