#### 24.2.2 compile-file-pathname [Function]

`compile-file-pathname` input-file &key output-file &allow-other-keys ⇒ pathname

#### Arguments and Values::

input-file—a pathname designator. (Default fillers for unspecified components are taken from *default-pathname-defaults*.)

output-file—a pathname designator. The default is implementation-defined.

pathname—a pathname.

#### Description::

Returns the pathname that compile-file would write into, if given the same arguments.

The defaults for the output-file are taken from the pathname that results from merging the input-file with the value of *default-pathname-defaults*, except that the type component should default to the appropriate implementation-defined default type for compiled files.

If input-file is a logical pathname and output-file is unsupplied, the result is a logical pathname.

If input-file is a logical pathname, it is translated into a physical pathname as if by calling translate-logical-pathname.

If input-file is a stream, the stream can be either open or closed. compile-file-pathname returns the same pathname after a file is closed as it did when the file was open.

It is an error if input-file is a stream that is created with make-two-way-stream, make-echo-stream, make-broadcast-stream, make-concatenated-stream, make-string-input-stream, make-string-output-stream.

If an implementation supports additional keyword arguments to compile-file, compile-file-pathname must accept the same arguments.

#### Examples::

See logical-pathname-translations.

#### Exceptional Situations::

An error of type file-error might be signaled if either input-file or output-file is wild.
