returning a value from a constructor
We ran into an interesting problem today. We tried to call the following
rtems_libio functions from a c++ constructor :
rtems_libio_check_fd( fd );
iop = rtems_libio_iop( fd );
The first and third generated the following errors :
/tcb2/rlc/source/char_available.c:55: returning a value from a constructor
/tcb2/rlc/source/char_available.c:57: returning a value from a constructor
This baffled us for a time until we realized that these two functions were
actually macros that contained returns for failure. We solved the problem
by calling a subroutine that called the two functions. If the two
functions were actually subroutines instead of macros the code would have
I know this would be a huge job and probably not worth the time but it
would be helpful if it was easy to tell macros from subroutines. One
method I've seen in the past is that all macros are capitalized.
Just wanted to get this into the archive in case someone else runs into
