digittoint —
convert a numeric character to its integer value
Standard C Library (libc, -lc)
#include
<ctype.h>
int
digittoint(int

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.
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.
