-/* Compile-time symbols that this file uses:
-
- HAVE_PSTAT_GETDYNAMIC Define this if your system has the
- pstat_getdynamic function. I think it
- is unique to HPUX9. The best way to get the
- definition is through the AC_FUNC_GETLOADAVG
- macro that comes with autoconf 2.13 or newer.
- If that isn't an option, then just put
- AC_CHECK_FUNCS(pstat_getdynamic) in your
- configure.in file.
- FIXUP_KERNEL_SYMBOL_ADDR() Adjust address in returned struct nlist.
- KERNEL_FILE Pathname of the kernel to nlist.
- LDAV_CVT() Scale the load average from the kernel.
- Returns a double.
- LDAV_SYMBOL Name of kernel symbol giving load average.
- LOAD_AVE_TYPE Type of the load average array in the kernel.
- Must be defined unless one of
- apollo, DGUX, NeXT, or UMAX is defined;
- otherwise, no load average is available.
- NLIST_STRUCT Include nlist.h, not a.out.h, and
- the nlist n_name element is a pointer,
- not an array.
- NLIST_NAME_UNION struct nlist has an n_un member, not n_name.
- LINUX_LDAV_FILE [__linux__]: File containing load averages.
-
- Specific system predefines this file uses, aside from setting
- default values if not emacs:
-
- apollo
- BSD Real BSD, not just BSD-like.
- convex
- DGUX
- eunice UNIX emulator under VMS.
- hpux
- __MSDOS__ No-op for MSDOS.
- NeXT
- sgi
- sequent Sequent Dynix 3.x.x (BSD)
- _SEQUENT_ Sequent DYNIX/ptx 1.x.x (SYSV)
- sony_news NEWS-OS (works at least for 4.1C)
- UMAX
- UMAX4_3
- VMS
- WINDOWS32 No-op for Windows95/NT.
- __linux__ Linux: assumes /proc filesystem mounted.
- Support from Michael K. Johnson.
- __NetBSD__ NetBSD: assumes /kern filesystem mounted.
-
- In addition, to avoid nesting many #ifdefs, we internally set
- LDAV_DONE to indicate that the load average has been computed.
-
- We also #define LDAV_PRIVILEGED if a program will require
- special installation to be able to call getloadavg. */
