sched_getparam(3)					     Library Functions Manual						 sched_getparam(3)

NAME
       sched_getparam - Returns the scheduling parameters of the specified process (P1003.1b)

LIBRARY
       Realtime Library (librt.so, librt.a)

SYNOPSIS
       #include <sched.h>

       int sched_getparam (
       pid_t pid,
       struct sched_param *param);

PARAMETERS
       pid     Specifies  the  ID  of the process for which scheduling parameters are to be returned. If pid is zero, the scheduling parameters of
	       the calling process are returned.

       *param  Specifies a pointer to a sched_param structure to receive the scheduling parameters of the specified process.  The  priority  field
	       receives the current priority of the process specified by the pid. The sched_param structure is defined in <sched.h>.

DESCRIPTION
       The  sched_getparam function returns the scheduling parameters of a process. If the pid is zero, the scheduling parameters are returned for
       the calling process.

       Use the sched_setparam function to change the scheduling parameters.

       Currently, the sched_param structure contains only a priority field.

       The priority of a process is inherited across fork and exec calls.

       No special privileges are needed to use the sched_getparam function.

RETURN VALUES
       On a successful call to the sched_getparam function, a value of 0 (zero) is returned. On an unsuccessful call, a value of  -1  is  returned
       and errno is set to indicate that an error occurred and that no scheduling parameters were returned.

ERRORS
       The sched_getparam function fails under the following conditions:

       [EINVAL]       Invalid  value  specified for the pid argument, the param pointer is NULL, or one or more of the parameters in it is outside
		      the valid range.

       [ESRCH]	      No process can be found corresponding to that specified by pid.
