The next +call to \fBdoupdate\fR restores the screen to the way it looked in the dump +file. + +The \fBscr_init\fR routine reads in the contents of \fIfilename\fR and uses +them to initialize the \fBcurses\fR data structures about what the terminal +currently has on its screen. If the data is determined to be valid, +\fBcurses\fR bases its next update of the screen on this information rather +than clearing the screen and starting from scratch. \fBscr_init\fR is used +after \fBinitscr\fR or a \fBsystem\fR [see \fBsystem\fR(BA_LIB)] call to share +the screen with another process which has done a \fBscr_dump\fR after its +\fBendwin\fR call. The data is declared invalid if the terminfo capabilities +\fBrmcup\fR and \fBnrrmc\fR exist; also if the terminal has been written to +since the preceding \fBscr_dump\fR call. + +The \fBscr_set\fR routine is a combination of \fBscr_restore\fR and +\fBscr_init\fR. It tells the program that the information in \fIfilename\fR is +what is currently on the screen, and also what the program wants on the screen. +This can be thought of as a screen inheritance function. + +To read (write) a window from (to) a file, use the \fBgetwin\fR and +\fBputwin\fR routines [see \fBcurs_util\fR(3X)]. +.SH RETURN VALUE +All routines return the integer \fBERR\fR upon failure and \fBOK\fR +upon success. +.SH NOTES +Note that \fBscr_init\fR, \fBscr_set\fR, and \fBscr_restore\fR may be macros. +.SH PORTABILITY +The XSI Curses standard, Issue 4, describes these functions (adding the const +qualifiers). + +The SVr4 docs merely say under \fBscr_init\fR that the dump data is also +considered invalid "if the time-stamp of the tty is old" but don't define +"old". +.SH SEE ALSO +\fBcurses\fR(3X), \fBcurs_initscr\fR(3X), \fBcurs_refresh\fR(3X), +\fBcurs_util\fR(3X), \fBsystem\fR(3S) +.\"# +.\"# The following sets edit modes for GNU EMACS +.\"# Local Variables: +.\"# mode:nroff +.\"# fill-column:79 +.\"# End: |
