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.
