NAME

 insch, winsch, mvinsch, mvwinsch - insert a character

SYNOPSIS

 
#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.
