Declaration of the GmThreadManager class.

Macro Definition Documentation

◆ GmThreadLocal

#define GmThreadLocal __thread

Macro used to declare that a global / static variable has a per thread value (Thread Local Storage)

IMPORTANT: The variable must be created BEFORE any thread criation. Space is not allocated for this variable in EXISTING threads (at least on Windows). This might be a problem if a thread local variable is declared in a DLL (plugin) loaded AFTER thread creation.

Enumeration Type Documentation

◆ GmThreadTaskResult

enum GmThreadTaskResult

Possible results for running a task.

Enumerator
GM_THREAD_OK	The thread finished its execution without errors.
GM_THREAD_CANCELED	The thread was externally canceled.
GM_THREAD_ABORTED	The thread aborted.

Variable Documentation

◆ GmThreadManagerThreadId

GmThreadLocal int GmThreadManagerThreadId

Local storage for thread ids. More efficient than using QThread::currentThread() for then accessing the thread id stored in the GmThread object.

Can not be a static member of GmThreadManager due to the GMC_API_EXPORT macro (thread variables can not have DLL interface).
