        !            37: .ft B
        !            38: This interface is not part of the C library.
        !            39: It has been placed in the Berkeley utility library, libutil, as it is
        !            40: used by several standard utilities.
        !            41: .ft R

        !            44: .I user_from_uid
        !            45: function returns the user name associated with the argument uid.
        !            46: The user name is cached so that multiple calls with the same uid 
        !            47: do not require additional calls to
        !            48: .IR getpwuid (3).
        !            49: If there is no user associated with the uid, a pointer is returned
        !            50: to an ASCII representation of the uid, unless the argument
        !            51: .I nouser
        !            52: is non-zero, in which case a NULL pointer is returned.

        !            55: .I group_from_gid
        !            56: function returns the group name associated with the argument gid.
        !            57: The group name is cached so that multiple calls with the same gid
        !            58: do not require additional calls to
        !            59: .IR getgrgid (3).
        !            60: If there is no group associated with the gid, a pointer is returned
        !            61: to an ASCII representation of the gid, unless the argument
        !            62: .I nogroup
        !            63: is non-zero, in which case a NULL pointer is returned.
