A *file descriptor* is a [[concept]] of [[UNIX]], and represents a
non-[[persistent|persistency]] handle to an object (a file, for example). With
respect to specific aspects, it is comparable to a [[capability]].
In a GNU Hurd system, the concept of file descriptors is based on object
handles (through [[Mach ports|microkernel/mach/port]]), and is [[implemented in
glibc|glibc/file_descriptor]].
