LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <ctype.h>

     int
     tolower(int c);

DESCRIPTION
     The tolower() function converts an upper-case letter to the corresponding
     lower-case letter.  For single C chars locales the value of the argument
     is representable as an unsigned char or the value of EOF.

RETURN VALUES
     If the argument is an upper-case letter, the tolower() function returns
     the corresponding lower-case letter if there is one; otherwise the argu-
     ment is returned unchanged.
