Class Method Summary
-
.getegid ⇒ Integer
mod_func
Alias for GID.eid.
-
.issetugid ⇒ Boolean
mod_func
Returns
true
if the process was created as a result of an execve(2) system call which had either of the setuid or setgid bits set (and extra privileges were given as a result) or if it has changed any of its real, effective or saved user or group IDs since it began execution. -
.setegid(group) ⇒ nil
mod_func
Set the effective group ID of the calling process to group.
-
.seteuid(user) ⇒ nil
mod_func
Set the effective user ID of the calling process to user.
-
.setgid(group) ⇒ nil
mod_func
Set the group ID of the current process to group.
-
.setregid(rid, eid) ⇒ nil
mod_func
Sets the (group) real and/or effective group IDs of the current process to rid and eid, respectively.
-
.setresgid(rid, eid, sid) ⇒ nil
mod_func
Sets the (group) real, effective, and saved user IDs of the current process to rid, eid, and sid respectively.
-
.setresuid(rid, eid, sid) ⇒ nil
mod_func
Sets the (user) real, effective, and saved user IDs of the current process to rid, eid, and sid respectively.
-
.setreuid(rid, eid) ⇒ nil
mod_func
Sets the (user) real and/or effective user IDs of the current process to rid and eid, respectively.
-
.setrgid(group) ⇒ nil
mod_func
