CURSES_FILEIO(3)        NetBSD Library Functions Manual       CURSES_FILEIO(3)


NAME

     curses_fileio, getwin, putwin -- curses file input/output routines


LIBRARY

     Curses Library (libcurses, -lcurses)


SYNOPSIS

     #include <curses.h>

     WINDOW *
     getwin(FILE *fp);

     int
     putwin(WINDOW *win, FILE *fp);


DESCRIPTION

     These functions read and write data to and from files.

     The getwin() function reads window data that has been stored in the file
     to which fp points, and then creates a new window using that data.

     The putwin() function writes window data from the window win to the file
     pointed to by fp.


RETURN VALUES

     The getwin() function returns one of the following values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.

     The putwin() function returns NULL if an error is detected.


SEE ALSO

     curses_window(3), fread(3), fwrite(3)


NOTES

     Subwindows can not be created by the getwin() function, nor written by
     the putwin() function.


STANDARDS

     The NetBSD Curses library complies with the X/Open Curses specification,
     part of the Single Unix Specification.
