# DESCRIPTION

These functions and macros locate and position cursors and windows.

The `getcury`() and `getcurx`() functions get the current row and column positions, respectively, of the cursor in the window win. The `getyx`() macro sets the values of y and x to the current row and column positions of the cursor in the window win.

The `getsyx`() macro sets the values of y and x of the current window if `is_leaveok`() is false, otherwise -1, -1. The `setsyx`() macro sets the row and column positions, respectively, of the cursor in the current window to the values of y and x. If both y and x are both -1 then `leaveok`() is set.

The origin row and columns of a window win can be determined by calling the `getbegy`() and `getbegx`() functions, respectively, and the maximum row and column for the window can be found by calling the functions `getmaxy`() and `getmaxx`(), respectively. The `getbegyx`() and `getmaxyx`() macros set the values of y and x to the origin and maximum row and column positions, respectively, for the window win.

The `getpary`() and `getparx`() functions return the row and column position of the given subwindow relative to the window's parent. The macro `getparyx`() sets the values of y and x to the origin of the subwindow relative to the window's parent.

The `move`() function positions the cursor on the current window at the position given by y, x. The cursor position is not changed on the screen until the next `refresh`().

The `wmove`() function is the same as the `move`() function, excepting that the cursor is moved in the window specified by win.

The function `mvcur`() moves the cursor to y, x on the screen. The arguments oldy, oldx define the previous cursor position for terminals that do not support absolute cursor motions. The curses library may optimise the cursor motion based on these values. If the `mvcur`() succeeds then the curses internal structures are updated with the new position of the cursor. If the destination arguments for `mvcur`() exceed the terminal bounds an error will be returned and the cursor position will be unchanged.

The `wcursyncup`() function sets the cursor positions of all ancestors of win to that of win.

# RETURN VALUES

Functions returning pointers will return `NULL` if an error is detected. The functions that return an int will return one of the following values:

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

# STANDARDS

The NetBSD Curses library complies with the X/Open Curses specification, part of the Single Unix Specification. The `getbegx`(), `getbegy`(), `getcurx`(), `getcury`(), `getmaxx`(), `getmaxy`(), `getparx`(), and `getpary`() functions are extensions.

# HISTORY

The Curses package appeared in 4.0BSD. The `getsyx`() and `setsyx`() functions are ncurses extensions to the Curses library and were added in NetBSD 8.0.
