/* Public Domain Curses */ #include <curspriv.h> RCSID("$Id: getyx.c,v 1.29 2008/07/15 17:13:26 wmcbrine Exp $") /*man-start************************************************************** Name: getyx Synopsis: void getyx(WINDOW *win, int y, int x); void getparyx(WINDOW *win, int y, int x); void getbegyx(WINDOW *win, int y, int x); void getmaxyx(WINDOW *win, int y, int x); void getsyx(int y, int x); int setsyx(int y, int x); int getbegy(WINDOW *win); int getbegx(WINDOW *win); int getcury(WINDOW *win); int getcurx(WINDOW *win); int getpary(WINDOW *win); int getparx(WINDOW *win); int getmaxy(WINDOW *win); int getmaxx(WINDOW *win); Description: The getyx() macro (defined in curses.h -- the prototypes here are merely illustrative) puts the current cursor position of the specified window into y and x. getbegyx() and getmaxyx() return the starting coordinates and size of the specified window, respectively. getparyx() returns the starting coordinates of the parent's window, if the specified window is a subwindow; otherwise it sets y and x to -1. These are all macros. getsyx() gets the coordinates of the virtual screen cursor, and stores them in y and x. If leaveok() is TRUE, it returns -1, -1. If lines have been removed with ripoffline(), then getsyx() includes these lines in its count; so, the returned y and x values should only be used with setsyx(). setsyx() sets the virtual screen cursor to the y, x coordinates. If y, x are -1, -1, leaveok() is set TRUE. getsyx() and setsyx() are meant to be used by a library routine that manipulates curses windows without altering the position of the cursor. Note that getsyx() is defined only as a macro. getbegy(), getbegx(), getcurx(), getcury(), getmaxy(), getmaxx(), getpary(), and getparx() return the appropriate coordinate or size values, or ERR in the case of a NULL window.
