SYNOPSIS
     ##iinncclluuddee <>

     int
     ddiiggiittttooiinntt(int c);

     ddiiggiittttooiinnttll(int c, localet loc);

DESCRIPTION
     The ddiiggiittttooiinntt() function converts a numeric character to its correspond-
     ing integer value.  The character can be any decimal digit or hexadecimal
     digit.  With hexadecimal characters, the case of the values does not mat-
     ter.

     While the ddiiggiittttooiinntt() function uses the current locale, the
     ddiiggiittttooiinnttll() function may be passed a locale directly. See xlocale(3)
     for more information.

RETURN VALUES
     The ddiiggiittttooiinntt() function always returns an integer from the range of 0
     to 15.  If the given character was not a digit as defined by isxdigit(3),
     the function will return 0.
