iswctype()

Test a wide character to see if it's a given character class

Synopsis:

#include <wctype.h>

int iswctype( wint_t wc, 
              wctype_t charclass );

Arguments:

wc: The wide character you want to test.
charclass: The character class you want to test for. Get this class by calling wctype().

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The iswctype() function tests if the argument wc is a member of one or several character classes. For example:

This function:	Is equivalent to:
`iswalnum(` `wc` `)`	`iswctype(` `wc, wctype( "alnum" ) )`
`iswalpha(` `wc` `)`	`iswctype(` `wc, wctype( "alpha" ) )`
`ispunct(` `wc` `)`	`iswctype(` `wc, wctype( "punct" ) )`

Note: The results are unreliable if you didn't use wctype() to obtain charclass, or if a call to setlocale() affects LC_CTYPE.

Returns:

A nonzero value if the character is a member of the specified character class (or classes), or zero if the character isn't a member or charclass is 0.

Classification:

ANSI, POSIX 1003.1

Safety:
Cancellation point	No
Interrupt handler	No
Signal handler	Yes
Thread	Yes

Caveats:

The result is valid only for wchar_t arguments and WEOF.
