Control characters are displayed in the <STRONG>^</STRONG><EM>X</EM> no- - tation. Printing characters are displayed as is. The - corresponding <STRONG>wunctrl</STRONG> returns a printable representation - of a wide character. - - The <STRONG>keyname</STRONG> routine returns a character string correspond- - ing to the key <EM>c</EM>: - - <STRONG>o</STRONG> Printable characters are displayed as themselves, - e.g., a one-character string containing the key. - - <STRONG>o</STRONG> Control characters are displayed in the <STRONG>^</STRONG><EM>X</EM> nota- - tion. - - <STRONG>o</STRONG> DEL (character 127) is displayed as <STRONG>^?</STRONG>. - - <STRONG>o</STRONG> Values above 128 are either meta characters (if the - screen has not been initialized, or if <STRONG>meta</STRONG> has - been called with a TRUE parameter), shown in the - <STRONG>M-</STRONG><EM>X</EM> notation, or are displayed as themselves. In - the latter case, the values may not be printable; - this follows the X/Open specification. - - <STRONG>o</STRONG> Values above 256 may be the names of the names of - function keys. - - <STRONG>o</STRONG> Otherwise (if there is no corresponding name) the - function returns null, to denote an error. X/Open - also lists an "UNKNOWN KEY" return value, which - some implementations return rather than null. - - The corresponding <STRONG>key_name</STRONG> returns a character string cor- - responding to the wide-character value <EM>w</EM>. The two func- - tions do not return the same set of strings; the latter - returns null where the former would display a meta charac- - ter. - - The <STRONG>filter</STRONG> routine, if used, must be called before <STRONG>initscr</STRONG> - or <STRONG>newterm</STRONG> are called. The effect is that, during those - calls, <STRONG>LINES</STRONG> is set to 1; the capabilities <STRONG>clear</STRONG>, <STRONG>cup</STRONG>, - <STRONG>cud</STRONG>, <STRONG>cud1</STRONG>, <STRONG>cuu1</STRONG>, <STRONG>cuu</STRONG>, <STRONG>vpa</STRONG> are disabled; and the <STRONG>home</STRONG> - string is set to the value of <STRONG>cr</STRONG>. - - The <STRONG>nofilter</STRONG> routine cancels the effect of a preceding - <STRONG>filter</STRONG> call. That allows the caller to initialize a - screen on a different device, using a different value of - <STRONG>$TERM</STRONG>. The limitation arises because the <STRONG>filter</STRONG> routine - modifies the in-memory copy of the terminal information. - - The <STRONG>use_env</STRONG> routine, if used, is called before <STRONG>initscr</STRONG> or - <STRONG>newterm</STRONG> are called. When called with <STRONG>FALSE</STRONG> as an argu- - ment, the values of <STRONG>lines</STRONG> and <STRONG>columns</STRONG> specified in the - <EM>terminfo</EM> database will be used, even if environment vari- - ables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> (used by default) are set, or if - <STRONG>curses</STRONG> is running in a window (in which case default be- - havior would be to use the window size if <STRONG>LINES</STRONG> and - <STRONG>COLUMNS</STRONG> are not set). Note that setting <STRONG>LINES</STRONG> or <STRONG>COLUMNS</STRONG> - overrides the corresponding size which may be obtained - from the operating system. - - The <STRONG>putwin</STRONG> routine writes all data associated with window - <EM>win</EM> into the file to which <EM>filep</EM> points. This information - can be later retrieved using the <STRONG>getwin</STRONG> function. - - The <STRONG>getwin</STRONG> routine reads window related data stored in the - file by <STRONG>putwin</STRONG>. The routine then creates and initializes - a new window using that data. It returns a pointer to the - new window. - - The <STRONG>delay_output</STRONG> routine inserts an <EM>ms</EM> millisecond pause - in output. This routine should not be used extensively - because padding characters are used rather than a CPU - pause. If no padding character is specified, this uses - <STRONG>napms</STRONG> to perform the delay. - - The <STRONG>flushinp</STRONG> routine throws away any typeahead that has - been typed by the user and has not yet been read by the - program. - - -</PRE> -<H2>RETURN VALUE</H2><PRE> - Except for <STRONG>flushinp</STRONG>, routines that return an integer re- - turn <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> (SVr4 specifies only "an in- - teger value other than <STRONG>ERR</STRONG>") upon successful completion. - - Routines that return pointers return <STRONG>NULL</STRONG> on error. - - X/Open does not define any error conditions. In this im- - plementation - - <STRONG>flushinp</STRONG> - returns an error if the terminal was not initial- - ized. - - <STRONG>meta</STRONG> returns an error if the terminal was not initial- - ized. - - <STRONG>putwin</STRONG> - returns an error if the associated <STRONG>fwrite</STRONG> calls - return an error. - - -</PRE> -<H2>PORTABILITY</H2><PRE> - The XSI Curses standard, Issue 4 describes these func- - tions. It states that <STRONG>unctrl</STRONG> and <STRONG>wunctrl</STRONG> will return a - null pointer if unsuccessful, but does not define any er- - ror conditions. This implementation checks for three cas- - es: - - <STRONG>o</STRONG> the parameter is a 7-bit US-ASCII code. This is - the case that X/Open Curses documented. - - <STRONG>o</STRONG> the parameter is in the range 128-159, i.e., a C1 - control code. If <STRONG>use_legacy_coding</STRONG> has been called - with a <STRONG>2</STRONG> parameter, <STRONG>unctrl</STRONG> returns the parameter, - i.e., a one-character string with the parameter as - the first character. Otherwise, it returns ``~@'', - ``~A'', etc., analogous to ``^@'', ``^A'', C0 con- - trols. - - X/Open Curses does not document whether <STRONG>unctrl</STRONG> can - be called before initializing curses. This imple- - mentation permits that, and returns the ``~@'', - etc., values in that case. - - <STRONG>o</STRONG> parameter values outside the 0 to 255 range. <STRONG>unc-</STRONG> - <STRONG>trl</STRONG> returns a null pointer. - - The SVr4 documentation describes the action of <STRONG>filter</STRONG> only - in the vaguest terms. The description here is adapted - from the XSI Curses standard (which erroneously fails to - describe the disabling of <STRONG>cuu</STRONG>). - - The strings returned by <STRONG>unctrl</STRONG> in this implementation are - determined at compile time, showing C1 controls from the - upper-128 codes with a `~' prefix rather than `^'. Other - implementations have different conventions. For example, - they may show both sets of control characters with `^', - and strip the parameter to 7 bits. Or they may ignore C1 - controls and treat all of the upper-128 codes as print- - able. This implementation uses 8 bits but does not modify - the string to reflect locale. The <STRONG>use_legacy_coding</STRONG> func- - tion allows the caller to change the output of <STRONG>unctrl</STRONG>. - - Likewise, the <STRONG>meta</STRONG> function allows the caller to change - the output of <STRONG>keyname</STRONG>, i.e., it determines whether to use - the `M-' prefix for ``meta'' keys (codes in the range 128 - to 255). Both <STRONG>use_legacy_coding</STRONG> and <STRONG>meta</STRONG> succeed only af- - ter curses is initialized. X/Open Curses does not docu- - ment the treatment of codes 128 to 159. When treating - them as ``meta'' keys (or if <STRONG>keyname</STRONG> is called before ini- - tializing curses), this implementation returns strings - ``M-^@'', ``M-^A'', etc. - - The <STRONG>keyname</STRONG> function may return the names of user-defined - string capabilities which are defined in the terminfo en- - try via the <STRONG>-x</STRONG> option of <STRONG>tic</STRONG>. This implementation auto- - matically assigns at run-time keycodes to user-defined - strings which begin with "k". The keycodes start at - KEY_MAX, but are not guaranteed to be the same value for - different runs because user-defined codes are merged from - all terminal descriptions which have been loaded. The - <STRONG>use_extended_names</STRONG> function controls whether this data is - loaded when the terminal description is read by the li- - brary. - - The <STRONG>nofilter</STRONG> routine is specific to ncurses. It was not - supported on Version 7, BSD or System V implementations. - It is recommended that any code depending on ncurses ex- - tensions be conditioned using NCURSES_VERSION. - - -</PRE> -<H2>SEE ALSO</H2><PRE> - <STRONG><A HREF="legacy_coding.3x.html">legacy_coding(3x)</A></STRONG>, <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, <STRONG><A HREF="curs_initscr.3x.html">curs_initscr(3x)</A></STRONG>, <STRONG>curs_ker-</STRONG> - <STRONG><A HREF="curs_kernel.3x.html">nel(3x)</A></STRONG>, <STRONG><A HREF="curs_scr_dump.3x.html">curs_scr_dump(3x)</A></STRONG>, <STRONG><A HREF="curs_variables.3x.html">curs_variables(3x)</A></STRONG>, <STRONG>lega-</STRONG> - <STRONG><A HREF="legacy_coding.3x.html">cy_coding(3x)</A></STRONG>. - - - - <STRONG><A HREF="curs_util.3x.html">curs_util(3x)</A></STRONG> -</PRE> -<HR> -<ADDRESS> -Man(1) output converted with -<a href="http://www.oac.uci.edu/indiv/ehood/man2html.html">man2html</a> -</ADDRESS> -</BODY> -</HTML> |
