Documentation
schedYield :: IO () Source
Running thread relinquishes control of its processor
schedGetScheduler :: Pid -> IO Int Source
Returns the scheduling policy of the process specified by Pid.
schedSetScheduler :: Pid -> Policy -> SchedParam -> IO () Source
Sets the scheduling policy and scheduling parameters of the process | specified by Pid to policy and the parameters specified schedParam. | The value of the schedPriority member in schedParam is any integer | within the inclusive priority range for the scheduling policy specified | by policy.
schedGetParam :: Pid -> IO SchedParam Source
Returns the scheduling parameters of a process specified by Pid | in schedParam.
schedSetParam :: Pid -> SchedParam -> IO () Source
Sets the scheduling parameters of the process specified by Pid to | the values specified by schedParam.
schedGetPriorityMin :: Policy -> IO Int Source
Returns the appropriate minimum for the scheduling policy specified | by Policy.
schedGetPriorityMax :: Policy -> IO Int Source
Returns the appropriate maximum for the scheduling policy specified | by Policy.
schedRRGetInterval :: Pid -> IO TimeSpec Source
Get Round Robin scheduling interval
