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 character can be any decimal digit or hexa-
     decimal 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.
