SYNOPSIS

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 charac‐
ter 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.
