+.SH DESCRIPTION
+.LP

+is undefined. If the argument of \fItolower\fP() represents
+an uppercase letter, and there exists a corresponding lowercase letter
+\ (as defined by character type information in the program
+locale category \fILC_CTYPE ),\fP the result shall be the
+corresponding lowercase letter. All other arguments in the domain
+are returned unchanged.
+.SH RETURN VALUE
+.LP
+Upon successful completion, \fItolower\fP() shall return the lowercase
+letter corresponding to the argument passed; otherwise,
+it shall return the argument unchanged.
