IServerTrackedDeviceProvider_Overview

IServerTrackedDeviceProvider is requested and used in vrserver to query tracking and other information about tracked devices. It must be implemented in driver dynamic libraries.

HmdError Init( IDriverLog *pDriverLog, vr::IServerDriverHost *pDriverHost, const char *pchUserDriverConfigDir, const char *pchDriverInstallDir )

initializes the driver. This will be called before any other methods are called. If Init returns anything other than HmdError_None the driver DLL will be unloaded.

• pchUserDriverConfigDir - The absolute path of the directory where the driver should store user config files.
• pchDriverInstallDir - The absolute path of the root directory for the driver.

void Cleanup()

Cleans up the driver right before it is unloaded.

uint32_t GetTrackedDeviceCount()

Returns the number of tracked devices that this driver manages that are physically connected. This is used at startup to initialize the tracked device list for the driver.

ITrackedDeviceServerDriver *GetTrackedDeviceDriver( uint32_t unWhich )

Returns a single tracked device interface.

ITrackedDeviceServerDriver* FindTrackedDeviceDriver( const char *pchId )

Returns a single tracked device by serial number.

void RunFrame()

Allows the driver do to some work in the main loop of the server. This can be useful to avoid the need for a main thread in your driver.
