System::Threading::Mutex class

Mutex class

Mutex implemnetation. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

class Mutex : public System::Threading::WaitHandle

Metode

Metode	Deskripsi
Mutex()	Informasi RTTI.
Mutex(bool)	Konstruktor.
Mutex(bool, const String&)	Konstruktor.
ReleaseMutex()	Melepaskan mutex.
static Remove(const String&)	Menghapus mutex bernama dari sistem.
virtual Reset()	Mengatur ulang status mutex. Tidak diimplementasikan.
virtual Set()	Mengatur mutex ke status tersinyal. Tidak diimplementasikan.
WaitOne() override	Mengunci mutex. Melakukan penunggu tak terbatas jika diperlukan.
WaitOne(int) override	Mengunci mutex. Melakukan penunggu jika diperlukan.
WaitOne(TimeSpan) override	Mengunci mutex. Melakukan penunggu jika diperlukan.

Bidang

Bidang	Deskripsi
static WaitTimeout	Nilai khusus yang akan dikembalikan oleh fungsi, selain mengembalikan indeks objek yang tersinyal dalam array, jika batas waktu terlampaui dan tidak ada yang menyinyal.
