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.
