Detailed Description

Non-refcounted RAII wrapper for FILE*.

Will automatically close the file when it goes out of scope if not null. If you're returning the file pointer, return file.release(). If you need to close the file early, use file.fclose() instead of fclose(file).

Get()

Get wrapped FILE* without transfer of ownership.

Note

Ownership of the FILE* will remain with this class. Use this only if the scope of the AutoFile outlives use of the passed pointer.

Note

This will invalidate the AutoFile object, and makes it the responsibility of the caller of this function to clean up the returned FILE*.
