Retrieve the list of supported viewfinder modes.
camera_error_t camera_get_supported_vf_modes(camera_handle_t handle, uint32_t numasked, uint32_t *numsupported, camera_vfmode_t *modes)
The handle returned by a call to the camera_open() function.
The requested number of viewfinder modes to return in the modes array. You can specify a value of 0 to determine the number of viewfinder modes supported.
A pointer to an integer that will be updated with the number of viewfinder modes supported.
A pointer to a camera_vfmode_t array. The array is updated with the list of viewfinder modes supported. Ensure that you allocate an array with the same number of elements as the numasked argument.
Library:libcamapi (For the qcc command, use the -l camapi option to link against this library)
Use this function to determine which viewfinder modes can be selected using the camera_set_vf_mode() function.
For more information about new and deprecated viewfinder functionality, see Viewfinder modes.
Ensure that the modes argument points to an array which has at least numasked elements allocated. To determine an appropriate size for this array, you can invoke this function in presizing mode by setting the numasked argument to 0 or the modes argument to NULL. When the function is invoked in this presizing mode, the maximum array size required is returned in the numsupported argument. You can then allocate an array of the appropriate size and invoke the function again with the numasked argument set to the value returned previously in the numsupported argument.
