std::iswpunct - cppreference.com (original) (raw)

Checks if the given wide character is a punctuation character, i.e. it is one of !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~ or any punctuation character specific to the current locale.

If the value of ch is neither representable as a wchar_t nor equal to the value of the macro WEOF, the behavior is undefined.

[edit] Parameters

[edit] Return value

Non-zero value if the wide character is a punctuation character, zero otherwise.

[edit] Notes

ISO 30112 specifies which Unicode characters are include in POSIX punct category.
