McOpenDriver

Establishes the communication of the application process with the MultiCam driver.

[C]

MCSTATUS McOpenDriver(
PCCHAR MultiCamName
);

Parameters

MultiCamName

This argument is reserved for future functionality. Specify a NULL pointer.

Remarks

If an application successfully calls McOpenDriver several times, it must call McCloseDriver the same number of times, to adequately close the communication with the MultiCam driver.
Starting with MultiCam 6, on Windows operating systems, MultiCam relies on a service named "MultiCam Service". This service is automatically started when the computer boots.
Software should only access MultiCam when this service is started. McOpenDriver will return MC_SERVICE_ERROR if the MultiCam service is not started when called.
To check when the service is started, the application has to call the McOpenDriver function in a loop until the function returns MC_OK.
Do not call McOpenDriver:
- inside the constructor of a global or static object;
- inside the DLL entry point (DllMain).
