# DESCRIPTION

These functions read and write data to and from files.

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

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

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

# 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.

# HISTORY

These functions first appeared in NetBSD 5.0.
