Details on the ls command and file types

Hey y'all,
I need some help with the nitty gritty of the ls command.

-First off in the man pages in the -l mode the first character can be "door" can anyone tell me what a door is???

-also in the -l mode the first character can be "fifo"or"pipe" can anyone tell me what a this is???

-What exactly does the -f option do? in the man pages it states: "forces each argument to be interpreted as a directory and list the name found in each slot" can someone give me an example of this???

-Does anyone by any remote chance know how ls determines columns based on the COLUMNS environment variable??

door_revoke(3DOOR)					      Door Library Functions						door_revoke(3DOOR)

NAME
door_revoke - revoke access to a door descriptor SYNOPSIS
cc -mt [ flag ... ] file ... -ldoor [ library ... ] #include <door.h> int door_revoke(int d); DESCRIPTION
The door_revoke() function revokes access to a door descriptor. Door descriptors are created with door_create(3DOOR). The door_revoke() function performs an implicit call to close(2), marking the door descriptor d as invalid. A door descriptor can only be revoked by the process that created it. Door invocations that are in progress during a door_revoke() invoca- tion are allowed to complete normally. RETURN VALUES
Upon successful completion, door_revoke() returns 0. Otherwise, door_revoke() returns -1 and sets errno to indicate the error. ERRORS
The door_revoke() function will fail if: EBADF An invalid door descriptor was passed. EPERM The door descriptor was not created by this process (with door_create(3DOOR)). ATTRIBUTES
