check-ps 1.2 alpha 5 has been released. This is a bugfix release. The upgrades
are:
o Linux compile fix applied
o Possible support for kill scanning on other platform (if pid_t is 16 bits
or ultra-fast machine it is probably supported, if not the program
probably says no).
o A configure script that works when fed to bash 2.x ('foo'$$'foo' expands
to foo$foo under bash 2.x which broke an awk script generated within the
script).
The maximum pid probing program is simplistic there are two stages. It is far
better to give it a header file that knows the real information.
1a. By doubling 1 repeated find when it goes negative or kill(n,0) returns
EINVAL (normally never).
1b. Give m= the last +ve value in the last step compute the biggest
+ve number by setting m=m+(m-1)
1c. If (overflowed and (m<0 or (m+1)>0)) say no.
2a. set a 1 second alarm
2b. Loop through 1 to m
2c. If the alarm went off the say no
2d. Otherwise report m+1
Anyone got a better method of finding the maxmimum possible pid?
