.Sh SYNOPSIS
|
|
.In unistd.h
|
|
.Ft int
|
|
.Fn getloginclass "char *name" "size_t len"
|

.Ft int
|

.Fn setloginclass "const char *name"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn getloginclass
|
|
routine returns the login class name associated with the calling process,
|
|
as previously set by
|
|
.Fn setloginclass .
|
|
The caller must provide the buffer
|
|
.Fa name
|
|
with length
|
|
.Fa len
|
|
bytes to hold the result.
|
|
The buffer should be at least
|
|
.Dv MAXLOGNAME
|
|
bytes in length.
|
|
.Pp
|
|
The
|
|
.Fn setloginclass
|
|
system call sets the login class of the calling process to
|
|
.Fa name .
|
|
This system call is restricted to the super-user, and is normally used
|
|
only when a new session is being created on behalf of the named user
|
|
(for example, at login time, or when a remote shell is invoked).
|
|
Processes inherit login class from their parents.
|
|
.Sh RETURN VALUES
|
|
.Rv -std
|
|
.Sh ERRORS
|
|
The following errors may be returned by these calls:
|
|
.Bl -tag -width Er
|
|
.It Bq Er EFAULT
|
|

|
|
.Fa name
|
|
argument gave an invalid address.
|
|
.It Bq Er EINVAL
|
|
The
|
|
.Fa name
|
|
argument pointed to a string that was too long.
|
|
Login class names are limited to
|
|
.Dv MAXLOGNAME
|
|
(from
|
|
.In sys/param.h )
|
|
characters, currently 17 including null.
|
|
.It Bq Er EPERM
|
|
The caller tried to set the login class and was not the super-user.
|
|
.It Bq Er ENAMETOOLONG
|
|
The size of the buffer is smaller than the result to be returned.
