/***********************************************************************
|
|
* 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.
