AbortNode()

bool AbortNode	(	const std::string &	strMessage,
		bilingual_str	user_message
	)

Abort with a message.

Definition at line 20 of file shutdown.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

AbortShutdown()

void AbortShutdown

(

)

Clear shutdown flag.

Only use this during init (before calling WaitForShutdown in any thread), or in the unit tests. Calling it in other circumstances will cause a race condition.

Here is the call graph for this function:

Here is the caller graph for this function:

fRequestShutdown()

static std::atomic< bool > fRequestShutdown ( false  )

static

Here is the caller graph for this function:

InitShutdownState()

bool InitShutdownState

(

)

Initialize shutdown state.

This must be called before using either StartShutdown(), AbortShutdown() or WaitForShutdown(). Calling ShutdownRequested() is always safe.

Here is the caller graph for this function:

ShutdownRequested()

bool ShutdownRequested

(

)

Returns true if a shutdown is requested, false otherwise.

Here is the caller graph for this function:

StartShutdown()

void StartShutdown

(

)

Request shutdown of the application.

Here is the call graph for this function:

Here is the caller graph for this function:

WaitForShutdown()

void WaitForShutdown

(

)

Wait for StartShutdown to be called in any thread.

This can only be used from a single thread.
