Get the priority of a given process
#include <sched.h> int getprio( pid_t pid );
libc
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(), pthread_setschedprio(), sched_get_priority_max(), sched_get_priority_min(), sched_getparam(), sched_getscheduler(), sched_setscheduler(), sched_yield(), setprio()
