local fs = require "filesystem"

fs.mode(user: integer, group: integer, other: integer) -> integer (1)
fs.mode("set_uid"|"set_gid"|"sticky_bit") -> integer (2)

Description

A helper function to create POSIX mode permission bits.

The implementation for overload #1 is:

function mode(user: integer, group: integer, other: integer) -> integer
    return bit.bor(bit.lshift(user, 6), bit.lshift(group, 3), other)
end

The meaning for overload #2’s parameters:

"set_uid": S_ISUID
"set_gid": S_ISGID
"sticky_bit": S_ISVTX
