Hello Oleg,
I use waitpid(PID:stat_loc:0) function to chek status but it always
return stat_loc = *zero but PID = ProcessID.
Your prototype for waitpid() is wrong. It should look like this:
D waitpid PR 10i 0 extproc('waitpid')
D pid 10i 0 value
D stat_loc 10I 0
D options 10I 0 value
The second parameter is an integer passed by reference. In C, it'll be
shown as "int *stat_loc" because, in C, you pass a pointer to a field in
order to pass it by reference. RPG passes by reference by default --
so you simply declare the integer parm with no special keywords in RPG.
You could potentially make a pointer work as well -- but not the way you
coded it -- and I suspect that's why it was not working for you.
