Function Documentation

changeCurrentProcessPriority()

void mrpt::system::changeCurrentProcessPriority

(

TProcessPriority

priority

)

Change the priority of the given process (it applies to all the threads, plus independent modifiers for each thread).

• Windows: See SetPriorityClass
• Linux (pthreads): Requires root permissions to increase process priority! Internally it calls nice(), so it has no effect if () was called and a SCHED_RR is already active.

  createThread, changeThreadPriority

Definition at line 109 of file scheduler.cpp.

changeCurrentThreadPriority()

void mrpt::system::changeCurrentThreadPriority

(

TThreadPriority

priority

)

Change the priority of the current thread - for Windows, see also changeCurrentProcessPriority()

• Windows: This is equivalent to SetThreadPriority() (read the docs there)
• Linux (pthreads): May require root permissions! This sets the Round Robin scheduler with the given priority level. Read sched_setscheduler.
