Example 7
List all the open files for the parent process.

pid_t target = getppid();

* next index after the current ’burst’
*/

Example 8
Acquire information about a specific LWP.
main()
{
struct lwp_status lwpbuf;
int count;
/*
* get information for LWP whose lwpid is 4321 within
* a process whose pid is 1234.
*/

0, 4321, 1234);
if ((count == -1) && (errno == ESRCH))
perror("pstat_getlwp(): cannot find given lwpid or pid");
else if (count == -1)
perror("pstat_getlwp()");
else {
/* process data from the call... */
(void)printf("processing lwp data...\n");
