+/***********************************************************************
+ * This function attempts to convert open flag bits into human readable
+ * symbols (i.e. O_TRUNC).  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.
+ *
+ * Return Value
+ * openflags2symbols will return the indentified symbols.
+ * If no symbols are recognized the return value will be a empty
+ * string or the "UNKNOWN" symbol.
+ *
+ * Limitations
+ * Currently (05/96) all known symbols are coded into openflags2symbols.
+ * If new open flags are added this code will have to updated
+ * to know about them or they will not be recognized.
+ *
+ * The Open_symbols must be large enough to hold all possible symbols
+ * for a given system.
