- The <STRONG>touchwin</STRONG> and <STRONG>touchline</STRONG> routines throw away all opti-
- mization information about which parts of the window have
- been touched, by pretending that the entire window has
- been drawn on. This is sometimes necessary when using
- overlapping windows, since a change to one window affects
- the other window, but the records of which lines have been
- changed in the other window do not reflect the change.
- The routine <STRONG>touchline</STRONG> only pretends that <EM>count</EM> lines have
- been changed, beginning with line <EM>start</EM>.
-
- The <STRONG>untouchwin</STRONG> routine marks all lines in the window as
- unchanged since the last call to <STRONG>wrefresh</STRONG>.
-
- The <STRONG>wtouchln</STRONG> routine makes <EM>n</EM> lines in the window, starting
- at line <EM>y</EM>, look as if they have (<EM>changed</EM><STRONG>=1</STRONG>) or have not
- (<EM>changed</EM><STRONG>=0</STRONG>) been changed since the last call to <STRONG>wrefresh</STRONG>.
-
- The <STRONG>is_linetouched</STRONG> and <STRONG>is_wintouched</STRONG> routines return <STRONG>TRUE</STRONG>
- if the specified line/window was modified since the last
- call to <STRONG>wrefresh</STRONG>; otherwise they return <STRONG>FALSE</STRONG>. In addi-
- tion, <STRONG>is_linetouched</STRONG> returns <STRONG>ERR</STRONG> if <EM>line</EM> is not valid for
- the given window.
