GETLOGINCLASS(2)	  FreeBSD System Calls Manual	      GETLOGINCLASS(2)

NAME
     getloginclass, setloginclass -- get/set login class

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <unistd.h>

     int
     getloginclass(char	*name, size_t len);

     int
     setloginclass(const char *name);

DESCRIPTION
     The getloginclass() routine returns the login class name associated with
     the calling process, as previously	set by setloginclass().	 The caller
     must provide the buffer name with length len bytes	to hold	the result.
     The buffer	should be at least MAXLOGNAME bytes in length.

     The setloginclass() system	call sets the login class of the calling
     process to	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.

RETURN VALUES
     Upon successful completion, the value 0 is	returned; otherwise the
     value -1 is returned and the global variable errno	is set to indicate the
     error.

ERRORS
     The following errors may be returned by these calls:

     [EFAULT]		The name argument gave an invalid address.

     [EINVAL]		The name argument pointed to a string that was too
			long.  Login class names are limited to	MAXLOGNAME
			(from <sys/param.h>) characters, currently 17 includ-
			ing null.

     [EPERM]		The caller tried to set	the login class	and was	not
			the super-user.

     [ENAMETOOLONG]	The size of the	buffer is smaller than the result to
			be returned.

     setusercontext(3)

HISTORY
     The getloginclass() and setloginclass() system calls first	appeared in
     FreeBSD 9.0.

FreeBSD	10.1			 March 6, 2011			  FreeBSD 10.1
