Get the priority of a given process
#include <sched.h>
int getprio( pid_t pid );
- pid
- The process ID of the process whose priority you want to get.

Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The getprio() function returns the current priority of
thread 1 in process pid. If pid is zero, the
priority of the calling thread is returned.
The priority, or -1 if an error occurred
(errno
is set).

The getprio() and setprio() functions are included in
the QNX Neutrino libraries for porting
QNX 4 applications.
For new programs, use
pthread_getschedparam().
errno,
pthread_getschedparam(),
pthread_setschedparam(),
sched_get_priority_max(),
sched_get_priority_min(),
sched_getparam(),
sched_getscheduler(),
sched_setscheduler(),
sched_yield(),
setprio()
