+.SH DESCRIPTION
+The above listed functions
+selects the minimum value of
+.I a
+and all follow arguments up to the first
+(and only)
+.I NULL
+argument (the so called
+.I NULL
+sentinel). For the functions with a
+.B va_list
+parameter, arguments are read from it.
+.PP
+The arguments after
+.I a
+or, for the functions with a
+.B va_list
+parameter, inside
+.I args
+must have the same type as
+.IR a ,
+except it can be
+.B const
+regardless of whether
+.I a
+is
+.BR const .
+.PP
+For the
+.BR libj2_min_j2i (),
+.BR libj2_vmin_j2i (),
+.BR libj2_min_j2u (),
+and
+.BR libj2_vmin_j2u ()
+functions, the minimum value is stored in
+.IR a .
+.PP
+For the
+.BR libj2_min_j2i_to_j2i (),
+.BR libj2_vmin_j2i_to_j2i (),
+.BR libj2_min_j2u_to_j2u (),
+and
+.BR libj2_vmin_j2u_to_j2u ()
+functions, the minimum value is stored in
+and argument, with the same type as
+.IR a ,
+except without the qualifier
+.BR const ,
+provided by the caller immediately after the
+.I NULL
+sentinel.
+.PP
+For the
+.BR libj2_min_j2i_return (),
+.BR libj2_vmin_j2i_return (),
+.BR libj2_min_j2u_return (),
+and
+.BR libj2_vmin_j2u_return ()
+functions, the argument with the minimum
+value is returned by the function. In the
+case that multiple arguments have the same
+value which is also the minimum value, one
+of the is returned arbitrarily. It is safe
+to remove the qualifier
+.BR const
+if you know that the argument with the
+minimum value did not have the qualifier
+.BR const
+const (it is the same pointer).
+.PP
+The arguments, except the sentinel in
+the varidic lists, are assumed to be
+.RI non- NULL .
+.RI ( a
+is assumed to be
+.RI non- NULL .)
+
+.SH RETURN VALUE
+For the
+.BR libj2_min_j2i_return (),
+.BR libj2_vmin_j2i_return (),
+.BR libj2_min_j2u_return (),
+and
+.BR libj2_vmin_j2u_return ()
+functions one of the arguments with the
+lowest value, is returned, for the
+other functions, there is no return value.
+
+.SH ERRORS
+The above listed functions cannot fail.
