Consider separate functions / fields to signal errors in Print write(), print(), println(). #598

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently, we've added ssize_t return types from write(), print(), and 
println().  It returns a negative number on error or the number of bytes 
written.  Instead, we might want to return just the number of bytes written, 
and use a separate function to get error if any.  For example, 
Print::clearWriteError() and Print::writeError() or similar.
