- These routines write the characters of the (null-termi- - nated) wchar_tcharacter 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. +
+ waddwstr writes the characters of the (wide-null-terminated) wide- + character string wstr to the window win. Its process is similar to + constructing a cchar_t for each wchar_t in wstr, then calling + wadd_wch(3x) with the resulting cchar_t. - The mv routines perform cursor movement once, before writ- - ing any characters. Thereafter, the cursor is advanced as - a side-effect of writing to the window. + o Spacing and non-spacing characters in the string are processed one + at a time, and - The four routines with n as the last argument write at - most n wchar_t characters.
