Mutexes to avoid collisions

If you are developing software which accesses hardware via low-level functions, you should use the following Win32 mutexes to avoid collisions with other software.

Right now these Mutexes are used by:

• CPU-Z http://www.cpuid.com/cpuz.php
• Everest http://www.lavalys.com
• Motherboard Monitor http://mbm.livewiredev.com
• Rivatuner http://www.guru3d.com/rivatuner
• SysTool http://systool.techpowerup.com
• SIVhttp://siv.mysite.orange.co.uk/index.html
• HWiNFO32 http://www.hwinfo.com/

• Motherboard ISA 0×290: Access_ISABUS.HTP.Method
• Motherboard SMBus: Access_SMBUS.HTP.Method
• ABIT UGuru: Access_ABIT_UGURU
• ATI VGA I2C bus: Access_ATI_I2C
• NVIDIA VGA I2C bus: Access_NV_I2C

declare:

HANDLE m_mutex;

During initialization of your application:

m_mutex = CreateMutex(NULL, FALSE, _T(EVENT_NAME));

Before you perform any low level operations, lock the event:

WaitForSingleObject(m_mutex,INFINITE);

When you are done, release the lock:

ReleaseMutex(m_mutex);

During application cleanup:

ReleaseMutex(m_mutex);
CloseHandle(m_mutex);

declare:

Var m_mutex : THandle;

During initialization of your application:

m_mutex := CreateMutex(Nil, False, EVENT_NAME);

Before you perform any low level operations, lock the event:

WaitforSingleObject(m_mutex,INFINITE);

When you are done, release the lock:

ReleaseMutex(m_mutex);

During application cleanup:

ReleaseMutex(m_mutex);
CloseHandle(m_mutex);
