    Integer to test.

Return Values

__isascii returns a non-zero value if c is an ASCII character (in the range 0x00 – 0x7F).

Each routine returns 0 if c does not satisfy the test condition.

The result of the test condition for the __isascii function depends on the LC_CTYPE category setting of the current locale.

For iswascii, the result of the test condition is independent of locale.
