KSTATE(2) LAM LOCAL LIBRARY KSTATE(2) NAME kstate - Get synchronization status of a LAM process. SYNOPSIS #include <kreq.h> int kstate (int pid, struct kstatus *status); DESCRIPTION The function kstate() enables a LAM process to inquire about the syn- chronization status of any process on the local node, including itself. The argument pid is the identifier of the process to be stated. The special identifier 0 indicates the calling process. Information returned from the daemon will be stored in(1,8) the structure addressed by the status argument. The structure is defined in(1,8) <kreq.h> as shown below. struct kstatus { int ks_state; int ks_priority; int ks_event; int ks_type; int ks_signal; int ks_flags; int ks_length; int ks_fyi[KNFYI]; }; Upon return from kstate(), the individual fields are filled with the information described below. ks_state scheduling status (see below) ks_priority synchronization priority (see kenter(2)) ks_event currently blocked or last used message event ks_type currently blocked or last used message type ks_signal pending signals to be delivered ks_flags internal process management flags ks_length currently blocked or last used message length ks_fyi application specific information The process states, defined in(1,8) <kreq.h>, are described below. KSREADY ready to run KSRECV blocked on krecv(2) to receive a message KSSEND blocked on ksend(2) to send(2,n) a message ERRORS ENOTPROCESS The process whose process identifier was passed to kstate() is not a LAM process. ENOTATTACHED The calling process is not a LAM process. SEE ALSO rpstate(2) LAM 7.0.6 May, 2004 KSTATE(2)
