Function heif_encoder_get_parameter

pub unsafe extern "C" fn heif_encoder_get_parameter(
    arg1: *mut heif_encoder,
    parameter_name: *const c_char,
    value_ptr: *mut c_char,
    value_size: c_int,
) -> heif_error

Get the current value of a parameter of any type as a human readable string. The returned string is compatible with heif_encoder_set_parameter().
