uint32_t GetOverlayKey( VROverlayHandle_t ulOverlayHandle, VR_OUT_STRING() char *pchValue, uint32_t unBufferSize, VROverlayError *pError = 0L )

Gets the string key from the specified overlay.

• VROverlayHandle_t ulOverlayHandle - The handle of the overlay to fetch a key for.
• char *pchValue - An application-provided buffer to put the key in.
• uint32_t unBufferSize - The size of the provided buffer. k_unVROverlayMaxKeyLength will be enough bytes to fit the string.
• VROverlayError *pError - Contains the result code of this request.

Description

Fills the provided buffer with the string key of the overlay. Returns the size of buffer required to store the key, including the terminating null character. k_unVROverlayMaxKeyLength will be enough bytes to fit the string.
