Redirect output from file to stdout

I have a program that can output its results only to files, with -o option. This time I need to output it to console, i.e. stdout. Here is my first try:

myprog -o /dev/stdout input_file

But it says:

/dev/ not writable

I’ve found this question that’s similar to mine, but /dev/stdout is obviously not going to work without some additional magic.

Q: How to redirect output from file to stdout?

P.S. Conventional methods without any specialized software are preferable.
