NAME
     digittoint, digittoint_l -- convert a numeric character to its integer
     value

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <ctype.h>

     int
     digittoint(int c);

     #include <ctype.h>

     int
     digittoint_l(int c, locale_t loc);

DESCRIPTION
     The digittoint() function converts a numeric character to its
     corresponding integer value.  The character can be any decimal digit or
     hexadecimal digit.  With hexadecimal characters, the case of the values
     does not matter.

     The digittoint_l() function takes an explicit locale argument, whereas
     the digittoint() function use the current global or per-thread locale.

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.
