sched_getparam()

get the current priority of a process

Synopsis:

#include <sys/sched.h>
int sched_getparam( pid_t pid,
                    struct sched_param *param );

Description:

The sched_getparam() function gets the current priority of the process specified by pid (or the current process if pid is zero), and puts it in the sched_priority member of the sched_param structure pointed to by param.

Returns:

0: Success
-1: An error occurred. errno is set to indicate the error.

Errors:

EPERM: The calling process doesn't have sufficient privilege to get the priority.
ESRCH: The process pid doesn't exist.

Classification:

POSIX 1003.4

Safety:
Interrupt handler	No
Signal handler	Yes, but modifies errno
Thread	Yes
