Example 14
Acquire the extended command line for the process.
main()
{
char cmdline[1024];
int rv;
(void)memset(&cmdline,0,sizeof(cmdline));
rv = pstat_getcommandline(cmdline, sizeof(cmdline),1, getpid());
if(rv<0){
perror("pstat_getcommandline()");
} else {
printf("Command line : %s \n",cmdline);
}
}
WARNINGS
Some parts of the program status may not get updated when a process becomes a zombie. An example is
the CPU percentage, which is not updated because the process is not expected to be scheduled to run after
entering the zombie state.
AUTHOR
The pstat_get*() routines were developed by HP.
