FileClose

FileClose

Description

Close a file we opened via FileOpen. Idempotent and safe on a borrowed (owns == false) handle; in that case it just clears the local state without touching the underlying fd / HANDLE.

Success

Returns true.

Failure

Returns false if the close syscall failed (logged).
