iterate through character classes

## NAME

**nextwctype** – iterate through character classes

Standard C Library (libc, -lc)

## SYNOPSIS

**#include \<wctype.h\>**

*wint\_t*\

**nextwctype**(*wint\_t ch*, *wctype\_t wct*);

## DESCRIPTION

The **nextwctype**() function determines the next character after *ch* that is a member of character class *wct*. If *ch* is -1, the search begins at the first member of *wct*.

## RETURN VALUES

The **nextwctype**() function returns the next character, or -1 if there are no more.
