/* 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.
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.
DGUX
eunice UNIX emulator under VMS.
hpux
- MSDOS No-op for MSDOS.
+ __MSDOS__ No-op for MSDOS.
NeXT
sgi
sequent Sequent Dynix 3.x.x (BSD)
UMAX
UMAX4_3
VMS
- WIN32 No-op for Windows95/NT.
+ WINDOWS32 No-op for Windows95/NT.
__linux__ Linux: assumes /proc filesystem mounted.
Support from Michael K. Johnson.
__NetBSD__ NetBSD: assumes /kern filesystem mounted.
