C Specification

The xrGetVirtualKeyboardDirtyTexturesMETA function is defined as:

// Provided by XR_META_virtual_keyboard
XrResult xrGetVirtualKeyboardDirtyTexturesMETA(
    XrVirtualKeyboardMETA                       keyboard,
    uint32_t                                    textureIdCapacityInput,
    uint32_t*                                   textureIdCountOutput,
    uint64_t*                                   textureIds);

Parameters

Parameter Descriptions
  • keyboard is the XrVirtualKeyboardMETA handle.

  • textureIdCapacityInput is the capacity of the textureIds array, or 0 to indicate a request to retrieve the required capacity.

  • textureIdCountOutput is filled in by the runtime with the count of texture IDs written or the required capacity in the case that textureIdCapacityInput is insufficient.

  • textureIds is the array of texture IDs that need to be updated.

Description

This function follows the two-call idiom for filling the textureIds array. Note that new texture data may be added after the runtime processes inputs from xrSendVirtualKeyboardInputMETA. Therefore, after sending new keyboard inputs the application should query the buffer size again before getting any texture data.
