redrawwin(3X)                                                 redrawwin(3X)

NAME
     redrawwin, wredrawln - line update status functions

SYNOPSIS
     cc [flag ...] file ... -lcurses [library ...]

     #include <curses.h>

     int redrawwin(WINDOW *win);

     int wredrawln(WINDOW *win, int begline, int numlines);

DESCRIPTION
     The redrawwin() and wredrawln() functions inform the implementation
     that some or all of the information physically displayed for the
     specified window may have been corrupted. The redrawwin() function
     marks the entire window; wredrawln() marks only numlines lines start-
     ing at line number begline. The functions prevent the next refresh
     operation on that window from performing any optimisation based on
     assumptions about what is physically displayed there.

RETURN VALUE
     Upon successful completion, these functions return OK. Otherwise they
     return ERR.

ERRORS
     No errors are defined.

NOTES
     The redrawwin() and wredrawln() functions could be used in a text edi-
     tor to implement a command that redraws some or all of the screen.
