6 | The fstat() system call in Bodhi OS retrieves metadata about an open file using its file descriptor. It provides information such as file size, permissions, and modification time without requiring a path lookup. This improves efficiency in file handling and enhances security by validating access rights. fstat() helps optimize system performance by streamlining file operations.
