-<H2>DESCRIPTION</H2><PRE>
- The <STRONG>unctrl</STRONG> macro expands to a character string which is a
- printable representation of the character <EM>c</EM>. Control
- characters are displayed in the <STRONG>^</STRONG><EM>X</EM> notation. Printing
- characters are displayed as is.
-
- The <STRONG>keyname</STRONG> routine returns a character string correspond-
- ing to the key <EM>c</EM>.
-
- 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>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
- behavior would be to use the window size if <STRONG>LINES</STRONG> and
- <STRONG>COLUMNS</STRONG> are not set).
-
- 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
- been typed by the user and has not yet been read by the
- program.

-<H2>RETURN VALUE</H2><PRE>
- Except for <STRONG>flushinp</STRONG>, routines that return an integer
- return <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> (SVr4 specifies only "an
- integer value other than <STRONG>ERR</STRONG>") upon successful completion.
-
- <STRONG>flushinp</STRONG> always returns <STRONG>OK</STRONG>.
-
- Routines that return pointers return <STRONG>NULL</STRONG> on error.
-
-
-</PRE>
-<H2>PORTABILITY</H2><PRE>
- The XSI Curses standard, Issue 4 describes these func-
- tions.
-
- 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>).
-

-<H2>NOTES</H2><PRE>
- Note that <STRONG>unctrl</STRONG> is a macro, which is defined in <<STRONG>unc-</STRONG>
- <STRONG>trl.h</STRONG>>.
