}
else
perror("pstat_getdynamic:");

That's because you are using the bundled C compiler that comes standard with the operating system. It's not ANSI C compliant and is primarily used for doing kernel builds. You need to purchase HP's ANSI-C product in order to compile and execute the C program successfully.
