                                                  unsigned int *numsupported,

Since:

BlackBerry 10.0.0

Arguments:

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

outputformat: The frame type that the viewfinder supports.

numasked: The requested number of photo resolutions to return in the resolutions array. You can use a value of 0 to determine the number of photo resolutions supported by the camera.

numsupported: The returned number of photo resolutions supported by the specified camera.

resolutions: A pointer to a camera_res_t array. The array is updated with the photo resolutions supported by the camera. Ensure that you allocate an array with the same number of elements as specified in the numasked argument.

Library:

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

Description:

After you use this function to retrieve the photo resolutions that are supported by the camera on the device, you can configure the photo size using camera_set_photo_property().

Ensure that the resolutions 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 resolutions 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.

Returns:
