Thanks for adding this, I think this should be added as both a subroutine and function since the documentation defines both versions (similar to how `getcwd` was added, see [this commit](https://github.com/llvm/llvm-project/commit/68413219dba47104fef388364a9973b584126f42#diff-61f662fe7491a12a18aefc00f674311004a4eae503a11cf10a8473a28e3ca9d2)).

Please also list this extension in flang/docs/Intrinsics.md.
