It is defined in the Unix module as an int. Perhaps some Obj.m= agic can do the trick?

For Windows however things are more complicat= ed, because a file_descr is a "struct filedescr" value. It is possible to o= btain an int from this using the win_CRT_fd_of_filedescr function or the CR= T_fd_val(v) macro, both defined in unixsupport.h.
I think you can either= use Obj.field or write a C function (basically calling win_CRT_fd_of_filedescr= ) to access this information.
