+ These functions write the (null-terminated) character string str on the + given window.

- All these entry points are described in the XSI Curses - standard, Issue 4.

+ All functions return the integer ERR upon failure and OK on success. + + X/Open does not define any error conditions. This implementation re- + turns an error + + o if the window pointer is null or + + o if the string pointer is null or + + o if the corresponding calls to waddch 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. If an error is returned by the wmove, no + characters are added to the window. + If an error is returned by waddch (e.g., because the window is not + large enough, or an illegal byte sequence was detected) only part of + the string may be added. Aside from that, there is a special case in + waddch where an error may be returned after successfully writing a + character to the lower-right corner of a window when scrollok is dis- + abled. +
+ All of these functions except waddnstr may be macros. +
