The <STRONG>scr_dump</STRONG> routine dumps the current contents of the <EM>virtual</EM> <EM>screen</EM>
to the file <EM>filename</EM>.
+
+</PRE><H3><a name="h3-scr_restore">scr_restore</a></H3><PRE>
The <STRONG>scr_restore</STRONG> routine sets the <EM>virtual</EM> <EM>screen</EM> to the contents of
<EM>filename</EM>, which must have been written using <STRONG>scr_dump</STRONG>. The next call
to <STRONG>doupdate</STRONG> restores the <EM>physical</EM> <EM>screen</EM> to the way it looked in the
dump file.
+
+</PRE><H3><a name="h3-scr_init">scr_init</a></H3><PRE>
The <STRONG>scr_init</STRONG> routine reads in the contents of <EM>filename</EM> and uses them to
initialize the <STRONG>curses</STRONG> data structures about what the terminal currently
has on its screen. If the data is determined to be valid, <STRONG>curses</STRONG> bases
its next update of the screen on this information rather than clearing
- the screen and starting from scratch. <STRONG>scr_init</STRONG> is used after <STRONG>initscr</STRONG>
- or a <STRONG>system</STRONG> call to share the screen with another process which has
- done a <STRONG>scr_dump</STRONG> after its <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG> call. The data is declared in-
- valid
+ the screen and starting from scratch. <STRONG>scr_init</STRONG> is used after
+ <STRONG><A HREF="curs_initscr.3x.html">initscr(3x)</A></STRONG> or a <STRONG>system(3)</STRONG> call to share the screen with another
+ process which has done a <STRONG>scr_dump</STRONG> after its <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG> call. The data
+ is declared invalid
<STRONG>o</STRONG> if the terminfo capabilities <STRONG>rmcup</STRONG> and <STRONG>nrrmc</STRONG> exist, also
<STRONG>o</STRONG> if the terminal has been written to since the preceding <STRONG>scr_dump</STRONG>
call.

The <STRONG>scr_set</STRONG> routine is a combination of <STRONG>scr_restore</STRONG> and <STRONG>scr_init</STRONG>. It
tells the program that the information in <EM>filename</EM> is what is currently
on the screen, and also what the program wants on the screen. This can
