DESCRIPTION
The digittoint() 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 digittoint() function uses the current locale, the
digittoint_l() function may be passed a locale directly. See xlocale(3)
for more information.
RETURN VALUES
The digittoint() 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.
