DIGITTOINT(3)            BSD Library Functions Manual            DIGITTOINT(3)

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 <xlocale.h>
     #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 charac-ter character
     ter can be any decimal digit or hexadecimal digit.  With hexadecimal characters, the case of the values
     does not matter.

     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.
