Tests for a blank wide-character code.
#include <wctype.h> int iswblank (wc) wint_t wc;
The iswblank subroutine tests whether the wc parameter is a wide-character code representing a character of class blank in the program's current locale.
The wc parameter is a wint_t, the value of which the application ensures is a wide-character code corresponding to a valid character in the current locale, or equal to the value of the macro WEOF. If the parameter has any other value, the behavior is undefined.
| wc | Specifies the value to be tested. |
The iswblank subroutine returns a nonzero value if the wc parameter is a blank wide-character code; otherwise, it returns a 0.
