Re^3: open(): Is there a simple way to map between numeric open modes and "symbol modes"?

in reply to Re^2: open(): Is there a simple way to map between numeric open modes and "symbol modes"?
in thread open(): Is there a simple way to map between numeric open modes and "symbol modes"? (solved)

As I remember, I "discovered" them by writing a small C program that open files in each of the modes and then queried the numeric value using this code (from Fmode.xs):

int 
xs_fmode( FILE *stream ) {
    return stream->_flag;
}

And I discovered that incantation by finding the struct FILE definition in the C header files.

NOTE: This was done using MSVC header files; YMMV on other platforms.
