| These functions copy the (null-terminated) array of complex characters |
| <EM>wchstr</EM> into the window image structure starting at the current cursor |
| position. |
| |
| The four functions with <EM>n</EM> as the last argument copy at most <EM>n</EM> elements, |
| but no more than will fit on the line. If <STRONG>n</STRONG>=<STRONG>-1</STRONG> then the whole array is |
| copied, to the maximum number of characters that will fit on the line. |
| |
| The window cursor is <EM>not</EM> advanced. These functions are faster than |
| <STRONG>waddnstr</STRONG>. On the other hand: |
| |
| <STRONG>o</STRONG> they do not perform checking (such as for the newline, backspace, |
| or carriage return characters), |
| |
| <STRONG>o</STRONG> they do not advance the current cursor position, |
| |
| <STRONG>o</STRONG> they do not expand other control characters to ^-escapes, and |
| |
| <STRONG>o</STRONG> they truncate the string if it crosses the right margin, rather |
| than wrapping it around to the new line. |
| |
| These functions end successfully on encountering a null <STRONG>cchar_t</STRONG>, or |
| when they have filled the current line. If a complex character cannot |
| completely fit at the end of the current line, the remaining columns |
| are filled with the background character and rendition. |
| |
| |
| </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE> |
| All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success. |
| |
| X/Open Curses does not specify any error conditions. This |
| implementation returns an error |
| |
| <STRONG>o</STRONG> if the <EM>win</EM> parameter is null or |
| |
| <STRONG>o</STRONG> if the <EM>wchstr</EM> parameter is null. |
| |
| Functions prefixed with "mv" first perform cursor movement and fail if |
| the position (<EM>y</EM>, <EM>x</EM>) is outside the window boundaries. |
| |

| All functions except <STRONG>wadd_wchnstr</STRONG> may be macros. |

| These functions are described in X/Open Curses, Issue 4. |
