getprio()

Get the priority of a given process

Synopsis:

#include <sched.h>

int getprio( pid_t pid );

Arguments:

pid

The process ID of the process whose priority you want to get.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

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.

Returns:

The priority, or -1 if an error occurred (errno is set).

Errors:

ESRCH

The process pid doesn't exist.

Classification:

QNX 4

Safety:
Cancellation point	No
Interrupt handler	No
Signal handler	Yes
Thread	Yes

Caveats:

The getprio() and setprio() functions are included in the QNX Neutrino libraries for porting QNX 4 applications. For new programs, use sched_getparam() or pthread_getschedparam().
