NAMEinch, winch, mvinch, mvwinch - get a curses character from a window SYNOPSIS#include <ncurses/curses.h> chtype inch(void); chtype winch(WINDOW *win); chtype mvinch(int y, int x); chtype mvwinch(WINDOW *win, int y, int x); DESCRIPTIONThese routines return the character, of type chtype, at the current position in the named window. If any attributes are set for that position, their values are OR'ed into the value returned. Constants defined in <curses.h> can be used with the & (logical AND) operator to extract the character or attributes alone. AttributesThe following bit masks may be AND-ed with characters returned by winch.
RETURN VALUEFunctions prefixed with “mv” first perform cursor movement and fail if the position (y, x) is outside the window boundaries. The winch function does not return an error if the window contains characters larger than 8-bits (255). Only the low-order 8 bits of the character are used by winch. NOTESNote that all of these routines may be macros. PORTABILITYThese functions are described in X/Open Curses, Issue 4. Very old systems (before standardization) provide a different function with the same name:
X/Open Curses does not specify the size and layout of attributes, color and character values in chtype; it is implementation-dependent. This implementation uses 8 bits for character values. An application using more bits, e.g., a Unicode value, should use the wide-character equivalents to these functions. SEE ALSOcurs_in_wch(3X) describes comparable functions of the ncurses library in its wide-character configuration (ncursesw). curses(3X), curs_instr(3X)
