| 71 | <H2>DESCRIPTION</H2><PRE> |
| 72 | These routines return a string of characters in <EM>str</EM>, |
| 73 | extracted starting at the current cursor position in the |
| 74 | named window. Attributes are stripped from the charac- |
| 75 | ters. The four functions with <EM>n</EM> as the last argument |
| 76 | return a leading substring at most <EM>n</EM> characters long |
| 77 | (exclusive of the trailing NUL). |
| 78 | |
| 79 | |
| 80 | </PRE> |
| 81 | <H2>RETURN VALUE</H2><PRE> |
| 82 | All of the functions return <STRONG>ERR</STRONG> upon failure, or the num- |
| 83 | ber of characters actually read into the string. |
| 84 | |
| 85 | X/Open defines no error conditions. In this implementa- |
| 86 | tion, if the window parameter is null or the str parameter |
| 87 | is null, a zero is returned. |
| 88 | |
| 89 | |
| 90 | </PRE> |
| 91 | <H2>NOTES</H2><PRE> |
| 92 | Note that all routines except <STRONG>winnstr</STRONG> may be macros. |
| 93 | |
| 94 | |
| 95 | </PRE> |
| 96 | <H2>PORTABILITY</H2><PRE> |
| 97 | SVr4 does not document whether a length limit includes or |
| 98 | excludes the trailing NUL. |
| 99 | |
| 100 | The ncurses library extends the XSI description by allow- |
| 101 | ing a negative value for <EM>n</EM>. In this case, the functions |
| 102 | return the string ending at the right margin. |
