Re: Does Linux has File Stream mapping support...?

Maybe an (ugly) way around it would be to simply use a parent process
which captures the stdout of your compiler and writes it to the log
file and prints it to its own stdout.

Now, a requirement came up which needs all those messages thrown to STDOUT also to be logged in a LOGFILE (in addition to STDOUT). Yes, this can be done through tee...but the usage model of the compiler doesn't leave that possibility open for me.
