rpstate − Report status of LAM processes on a remote node.
#include <preq.h>
int rpstate(int node, int sflags, int svalue, struct pstate *stat_tab, int maxsize); |
Selection
Methods
Processes to be reported from the target node are selected
by one of several methods, chosen in the sflags
argument. The selection method codes are defined in
<preq.h>.
SELECT_PID |
Select by process ID. The svalue argument contains the process ID. | ||
SELECT_INDEX |
Select by process table index. The svalue argument contains the index. | ||
SELECT_APPL |
Select all application (user) processes. | ||
SELECT_SYS |
Select all system processes. | ||
SELECT_ALL |
Select all application and all system processes. |
Remote
Process Status
The status structure array, stat_tab, is filled with
information on the selected processes. The structure is
defined in <preq.h>.
struct pstate {
int |
ps_reply; | |
int |
ps_index; | |
int |
ps_pid; | |
int |
ps_rtf; | |
int |
ps_nodeid; | |
int |
ps_event; | |
struct kstatus |
ps_kernel; | |
char |
ps_name[PSMAXNAME]; | |
char |
ps_loadpt[PSMAXNAME]; |
};
ps_reply |
internal use by rpstate() | ||
ps_index |
index within target node | ||
ps_pid |
identifier within target node | ||
ps_rtf |
runtime flags, see rploadgo(2) | ||
ps_nodeid |
parent’s node identifier | ||
ps_event |
parent’s event for reporting process’s exit | ||
ps_kernel |
kernel status, see kstate(2) | ||
ps_name |
argv[0], usually the program name, see kenter(2) | ||
ps_loadpt |
load module filename |
Upon successful completion, the number of selected processes is returned. This could be more or less than maxsize. If an error occurred, −1 is returned and the global variable errno is set to indicate the error.
