| <H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE> |
| These functions copy the (null-terminated) array of com- |
| plex characters <EM>wchstr</EM> into the window image structure |
| starting at the current cursor position. The four func- |
| tions 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 work |
| 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 ^-es- |
| capes, and |
| |
| <STRONG>o</STRONG> they truncate the string if it crosses the right mar- |
| gin, rather than wrapping it around to the new line. |
| |
| These functions end successfully on encountering a null |
| <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>, 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 does not define any error conditions. This imple- |
| mentation returns an error if the window pointer is null. |
| |
| Functions with a "mv" prefix first perform a cursor move- |
| ment using <STRONG>wmove</STRONG>, and return an error if the position is |
| outside the window, or if the window pointer is null. |

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