If there - * are more than one symbol, the <sep> string will be placed as - * a separator between symbols. Commonly used separators would - * be a comma "," or pipe "|". If <mode> is one and not all - * <openflags> bits can be converted to symbols, the "UNKNOWN" - * symbol will be added to return string. - * Openflags2symbols will return the indentified symbols. - * If no symbols are recognized the return value will be a empty - * string or the "UNKNOWN" symbol. - * - * SPECIAL REQUIREMENTS - * None. - * - * UPDATE HISTORY - * This should contain the description, author, and date of any - * "interesting" modifications (i.e. info should helpful in - * maintaining/enhancing this module). - * username description - * ---------------------------------------------------------------- - * rrl This code was first created during the beginning - * of the SFS testing days.
