22/* Compile-time symbols that this file uses:
23
24 HAVE_PSTAT_GETDYNAMIC Define this if your system has the
25 pstat_getdynamic function. I think it
26 is unique to HPUX9. The best way to get the
27 definition is through the AC_FUNC_GETLOADAVG
28 macro that comes with autoconf 2.13 or newer.
29 If that isn't an option, then just put
30 AC_CHECK_FUNCS(pstat_getdynamic) in your
31 configure.in file.
32 HAVE_LIBPERFSTAT Define this if your system has the
33 perfstat_cpu_total function in libperfstat (AIX).
34 FIXUP_KERNEL_SYMBOL_ADDR() Adjust address in returned struct nlist.
35 KERNEL_FILE Name of the kernel file to nlist.
36 LDAV_CVT() Scale the load average from the kernel.
37 Returns a double.
38 LDAV_SYMBOL Name of kernel symbol giving load average.
39 LOAD_AVE_TYPE Type of the load average array in the kernel.
40 Must be defined unless one of
41 apollo, DGUX, NeXT, or UMAX is defined;
42 or we have libkstat;
43 otherwise, no load average is available.
44 HAVE_NLIST_H nlist.h is available. NLIST_STRUCT defaults
45 to this.
46 NLIST_STRUCT Include nlist.h, not a.out.h.
47 N_NAME_POINTER The nlist n_name element is a pointer,
48 not an array.
49 HAVE_STRUCT_NLIST_N_UN_N_NAME `n_un.n_name' is member of `struct nlist'.
50 LINUX_LDAV_FILE [__linux__, __CYGWIN__]: File containing
51 load averages.

54 default values if not emacs:

74 __CYGWIN__ Cygwin emulates linux /proc/loadavg.
75 __NetBSD__ NetBSD: assumes /kern file system mounted.
76
77 In addition, to avoid nesting many #ifdefs, we internally set
78 LDAV_DONE to indicate that the load average has been computed.
79
