DESCRIPTION
These functions write the characters of the (null-terminated) wchar_t character string wstr on the given window. It is similar to constructing a cchar_t for each wchar_t in the string, then calling wadd_wch for the resulting cchar_t.The mv functions perform cursor movement once, before writing any characters. Thereafter, the cursor is advanced as a side-effect of writing to the window.
The four functions with n as the last argument write at most n wchar_t characters, or until a terminating null is reached. If n is -1, then the entire string will be added.
RETURN VALUE
All functions return the integer ERR upon failure and OK on success.X/Open does not define any error conditions. This implementation returns an error
- if the window pointer is null or
- if the string pointer is null or
- if the corresponding calls to wadd_wch return an error.
Functions with a "mv" prefix first perform a cursor movement using wmove, and return an error if the position is outside the window, or if the window pointer is null.
