    ref_buffer: *const c_void,
    ref_buffer_size: i32,
    num_row: i64,
    num_classes: i32,

Arguments

• ref_buffer - A binary representation of the dataset schema (feature groups, bins, etc.)
• ref_buffer_size - The size of the reference array in bytes
• num_row - Number of total rows the dataset will contain
• num_classes - Number of classes (will be used only in case of multiclass and specifying initial scores)
• parameters - Additional parameters
• out (direction out) - Created dataset

Returns
