console output

Hi there.

I am making 2 types of interfaces for an application, a GUI and a command interface which will take some parameters

now, through the GUI, if any errors occur while it is processing its stuff, it will write to a log file.

the command interface will also have this option, however i am planning to provide the user with the option to log errors on the screen, not just the error log file.

how is it possible to direct the error logging to one console or another through both?

the GUI is a seperate interface
The command line is a seperate interface
The main processing is a seperate interface

the main processing interface will write errors to an error log file

but how can i tell that to redirect the output to the screen, or maybe tell the command line to redirect it internally

any ideas?

or should i just give it a parameter internally, where when it is creating or setting the output file, to set it according to the parameter, such as if it should be a console or a file?


Thanks!

just pass parameter telling what to output to and just use a normal switch statement and code as necessary.
