bool Ogre::Timer::setOption const String strKey,
const void *  pValue
 

Method for setting a specific option of the Timer.

These options are usually specific for a certain implementation of the Timer class, and may (and probably will) not exist across different implementations. reset() must be called after all setOption() calls.

Current options supported are:
  • "QueryAffinityMask" (DWORD): Set the thread affinity mask to be used to check the timer. If 'reset' has been called already this mask should overlap with the process mask that was in force at that point, and should be a power of two (a single core).
Parameters:
strKey The name of the option to set
pValue A pointer to the value - the size should be calculated by the timer based on the key
Returns:
On success, true is returned.
On failure, false is returned.

bool Ogre::Timer::setOption const String strKey,
const void *  pValue
 

Method for setting a specific option of the Timer.

These options are usually specific for a certain implementation of the Timer class, and may (and probably will) not exist across different implementations. reset() must be called after all setOption() calls.

Parameters:
strKey The name of the option to set
pValue A pointer to the value - the size should be calculated by the timer based on the key
Returns:
On success, true is returned.
On failure, false is returned.
