Function SetThreadPriority

SetThreadPriority sets the priority of the given thread relative to a Base. The Base is the value RTKConfig.MainPriority, RTKConfig.DefaultPriority, or the current task's priority (the first non-zero value is used). The priority is changed as follows:

Parameter nPriority	Priority
THREAD_PRIORITY_IDLE	Base - 3
THREAD_PRIORITY_LOWEST	Base - 2
THREAD_PRIORITY_BELOW_NORMAL	Base - 1
THREAD_PRIORITY_NORMAL	Base
THREAD_PRIORITY_ABOVE_NORMAL	Base + 1
THREAD_PRIORITY_HIGHEST	Base + 2
THREAD_PRIORITY_TIME_CRITICAL	Base + 3

If the resulting priority is below RTK_MIN_PRIO, RTK_MIN_PRIO is used instead. If the resulting priority is above RTK_MAX_PRIO, RTK_MAX_PRIO is used instead.

RTKConfig.MainPriority defaults to 5. This makes the range of priorities 2 to 8 available to Win32 threads.
