Test a wide character to see if it's a blank character
#include <wctype.h> int iswblank( wint_t wc );
- The wide character you want to test. This argument must be a wide-character code that corresponds to a valid character in the current locale, or must be WEOF; otherwise, the function's behavior is undefined.
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The iswblank() function tests if the argument wc is a wide character of the class blank. In the C locale, this class includes the space character and \t (horizontal tab).
A nonzero value if the character is a member of the class blank, or 0 otherwise.
The result is valid only for wchar_t arguments and WEOF.
