:relfileprefix: ../../../
:mrdocs:

Append the specified `filename` up to the optionally specified `length` to the end of the specified `path`. If `length` is negative, append the entire string. If the optionally specified `rootEnd` offset is non‐negative, it is taken as the position in `path` of the character following the root. The behavior is undefined if `filename` represents an absolute path or if either `filename` or `path` ends with the filesystem separator character. The behavior is also undefined if `filename` points to any part of `path` (i.e., `filename` may not be an alias for `path`). See []and Performance).
