camera_get_flash_level()

Retrieve the flash power level.

Synopsis:

#include <camera/camera_api.h>
 
camera_error_t camera_get_flash_level(camera_handle_t handle,                 
                                      uint32_t *percent)

Since:

BlackBerry 10.0.0

Arguments:

handle

The handle returned by a call to the camera_open() function.

percent

A pointer to the returned percentage value.

Library:

libcamapi (For the qcc command, use the -l camapi option to link against this library)

Description:

Use this function to get the available flash power level, as a percentage of the maximum. A non-zero level indicates that there is sufficient power available to fire the flash (see camera_config_flash()). You can listen for CAMERA_STATUS_FLASH_LEVEL_CHANGE status events to know when the flash power level has changed from its previous value.

The viewfinder must be running before using this function.

Returns:

CAMERA_EOK when the function successfully completes, otherwise another camera_error_t value that provides the reason that the call failed.
