Return Type : int

Integer type (typically 4 bytes, -2,147,483,648 to 2,147,483,647)

Read about return values of iswalnum function .

1st Parameter Type : wint_t

An integer type capable of storing any wide character value or the special value WEOF, used in wide-character input/output functions.

1st Parameter

The wide character to be tested, passed as a `wint_t`

The iswalnumfunction in C language Checks whether the wide character is alphanumeric.

The iswalnum function tests whether wc is a wide character code representing an alphanumeric character (a letter or digit).

The iswalnumfunction takes 1 parameter:

•
wint_t `wc`: The wide character to be tested, passed as a `wint_t`

Checks if the given wide character `wc` is an alphanumeric wide character (a letter or a digit). Returns a nonzero value if `wc` is alphanumeric, and `0` otherwise.

The iswalnum function return value :

Returns non-zero if the wide character is alphanumeric, 0 otherwise

Output

This example demonstrates basic usage of iswalnum with various wide characters, including non-Latin scripts.
