.Dd March 6, 2011 .Dt GETLOGINCLASS 2 .Os .Sh NAME .Nm getloginclass , .Nm setloginclass .Nd get/set login class .Sh LIBRARY .Lb libc .Sh SYNOPSIS n 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.
p 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: l -tag -width Er t Bq Er EFAULT The .Fa name argument gave an invalid address. t Bq Er EINVAL The .Fa name argument pointed to a string that was too long. Login class names are limited to .Dv MAXLOGNAME (from n sys/param.h ) characters, currently 17 including null. t Bq Er EPERM The caller tried to set the login class and was not the super-user. t Bq Er ENAMETOOLONG The size of the buffer is smaller than the result to be returned. .El .Sh SEE ALSO .Xr setusercontext 3 .Sh HISTORY The .Fn getloginclass and .Fn setloginclass system calls first appeared in .Fx 9.0 .
