Obtains a handle for valid property names in the current locale for wide characters.
Standard C library (libc.a).
wctype_t wctype (Property) const char *Property;
wctype_t get_wctype (Property) char *Property;
The wctype subroutine obtains a handle for valid property names for wide characters as defined in the current locale. The handle is of data type wctype_t and can be used as the WC_PROP parameter in the iswctype subroutine. Values returned by the wctype subroutine are valid until the setlocale subroutine modifies the LC_CTYPE category. The get_wctype subroutine is identical to the wctype subroutine.
|Property|| Points to a string that identifies a generic character class for
which code set-specific information is required. The basic character classes
Upon successful completion, the subroutine returns a value of type wctype_t, which is a handle for valid property names in the current locale. Otherwise, it returns a value or - 1 if the Property parameter specifies a character class that is not valid for the current locale.
This subroutine is part of Base Operating System (BOS) Runtime.
The wctype subroutine adheres to Systems Interface and Headers, Issue 4 of X/Open.
