	Arch specific thread context. More...

union {
struct {

}   sleep
	For sleeping threads only.
};
	Information relative to the current state of the thread.

Detailed Description

The struct contains information about the thread's execution state. This state is architecture dependant, so its actual definition is present inside the arch specific process header file.

Generic information about a thread include its current state (used by the scheduler), information about its containing process and feature flags.

Containing process

state
