Expand description
Thread priority enumeration.
Variants
Min
Holds a value representing the minimum possible priority.
The ThreadPriority::Min
value is mapped to WinAPIThreadPriority::Lowest
and not
WinAPIThreadPriority::Idle
to avoid unexpected drawbacks. Use the specific value
to set it to WinAPIThreadPriority::Idle
when it is really needed.
Crossplatform(ThreadPriorityValue)
Holds a platform-independent priority value. Usually used when setting a value, for sometimes it is not possible to map the operating system’s priority to this value.
Os(ThreadPriorityOsValue)
Holds an operating system specific value. If it is not possible to obtain the
ThreadPriority::Crossplatform
variant of the value, this is returned instead.
The value is matched among possible values in Windows from WinAPIThreadPriority::Idle
till
WinAPIThreadPriority::TimeCritical
. This is due to windows only having from 7 to 9 possible
thread priorities and not 100
as it is allowed to have in the ThreadPriority::Crossplatform
variant.
Max
Holds a value representing the maximum possible priority.
Should be used with caution, it solely depends on the target
os where the program is going to be running on, how it will
behave. On some systems, the whole system may become frozen
if not used properly.
The ThreadPriority::Max
value is mapped to WinAPIThreadPriority::Highest
and not
WinAPIThreadPriority::TimeCritical
to avoid unexpected drawbacks. Use the specific value
to set it to WinAPIThreadPriority::TimeCritical
when it is really needed.
