Yes. You can use:
cat file1 file2 file3 | my_app /dev/stdin
or:
my_app <(cat file1 file2 file3)
In the latter case, the argument actually passed to my_app is of
the form "/dev/fd/63". bash sets up the pipe on an arbitrary
file descriptor and passes the corresponding /dev/fd/* argument.
In either case, caveats about seeking in a pipe apply.
