.SH DESCRIPTION
|
||
|
|
.I Eve
|
||
|
|
is a null-terminated string containing the name of the owner of
|
||
|
|
the Plan 9 system (sometimes called the `host owner',
|
||
|
|
see
|
||
|
|
.IR cons (3)).
|
||
|
|
The identity is set on a terminal to the name of the user who logs in.
|
||
|
|
It is set on a CPU server to the
|
||
|
|
.I authid
|
||
|
|
obtained either from NVRAM or by a console prompt.
|
||
|
|
The initial process created by system initialisation is given the
|
||
|
|
.I eve
|
||
|
|
identity.
|
||
|
|
.PP
|
||
|
|
.I Iseve
|
||
|
|
returns true if the current user is
|
||
|
|
.IR eve .
|
||
|
|
Several drivers use
|
||
|
|
.I iseve
|
||
|
|
to check the caller's identity
|
||
|
|
before granting permission to perform certain actions.
|
||
|
|
For example, the console driver allows only the user
|
||
|
|
.I eve
|
||
|
|
to write a new identity into the
|
||
|
|
.B /dev/user
|
||
|
|
file.
|
||
|
|
The privileges are strictly local and do not extend into the network
|
||
|
|
(in particular, to file servers—even ones running on the local machine).
