(ENHANCED CURSES)

NAME

mvderwin — deﬁne window coordinate transformation

SYNOPSIS

#include <curses.h>

int mvderwin(WINDOW *win, int par_y, int par_x);

DESCRIPTION

The mvderwin() function speciﬁes a mapping of characters. The function identiﬁes a mapped area of the

parent of the speciﬁed window, whose size is the same as the size of the speciﬁed window and whose origin

is at (par_y, par_x) of the parent window.

• During any refresh of the speciﬁed window, the characters displayed in that window’s display area

of the terminal are taken from the mapped area.

• Any references to characters in the speciﬁed window obtain or modify characters in the mapped

area.

That is, mvderwin() deﬁnes a coordinate transformation from each position in the mapped area to a

corresponding position (same y, x offset from the origin) in the speciﬁed window.

RETURN VALUE

Upon successful completion,

mvderwin() returns OK. Otherwise, it returns ERR.

ERRORS

No errors are deﬁned.
