INSCH(3XCURSES) X/Open Curses Library Functions INSCH(3XCURSES)

NAME

insch, winsch, mvinsch, mvwinsch - insert a character

SYNOPSIS

cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
-R /usr/xpg4/lib -lcurses [ library... ]

c89 [ flag... ] file... -lcurses [ library... ]

#include <curses.h>

int insch(chtype ch);


int mvinsch(int y, int x, chtype ch);


int mvwinsch(WINDOW *win, int y, int x, chtype ch);


int winsch(WINDOW *win, chtype ch);

PARAMETERS

ch
Is the character to be inserted.


y
Is the y (row) coordinate of the position of the character.


x
Is the x (column) coordinate of the position of the character.


win
Is a pointer to the window in which the character is to be
inserted.

DESCRIPTION

These functions insert the character and rendition from ch into the
current or specified window at the current or specified position.


These functions do not perform wrapping and do not advance the cursor
position. These functions perform special-character processing, with the
exception that if a newline is inserted into the last line of a window
and scrolling is not enabled, the behavior is unspecified.

RETURN VALUES

Upon successful completion, these functions return OK. Otherwise, they
return ERR.

ERRORS

No errors are defined.

USAGE

These functions are only guaranteed to operate reliably on character sets
in which each character fits into a single byte, whose attributes can be
expressed using only constants with the A_ prefix.
