char *unctrl(chtype c);

void use_env(char bool);
int putwin(WINDOW *win, FILE *filep);

int delay_output(int ms);
The unctrl macro expands to a character string which is a
printable representation of the character c. Control
characters are displayed in the ^X notation. Printing
characters are displayed as is.
The keyname routine returns a character string correspond-
ing to the key c.
The filter routine, if used, must be called before initscr
or newterm are called. The effect is that, during those
calls, LINES is set to 1; the capabilities clear, cup,
cud, cud1, cuu1, cuu, vpa are disabled; and the home
string is set to the value of cr.
The use_env routine, if used, is called before initscr or
newterm are called. When called with FALSE as an argu-
ment, the values of lines and columns specified in the
terminfo database will be used, even if environment vari-
ables LINES and COLUMNS (used by default) are set, or if
curses is running in a window (in which case default
behavior would be to use the window size if LINES and
COLUMNS are not set).
The putwin routine writes all data associated with window
win into the file to which filep points. This information
can be later retrieved using the getwin function.
The getwin routine reads window related data stored in the
file by putwin. The routine then creates and initializes
a new window using that data. It returns a pointer to the
The delay_output routine inserts an ms millisecond pause
in output. This routine should not be used extensively
because padding characters are used rather than a CPU
The flushinp routine throws away any typeahead that has
been typed by the user and has not yet been read by the
Except for flushinp, routines that return an integer
return ERR upon failure and OK (SVr4 specifies only "an
integer value other than ERR") upon successful completion.
flushinp always returns OK.
Routines that return pointers return NULL on error.
The XSI Curses standard, Issue 4 describes these func-
The SVr4 documentation describes the action of filter only
in the vaguest terms. The description here is adapted
from the XSI Curses standard (which erroneously fails to
describe the disabling of cuu).
Note that unctrl is a macro, which is defined in <unc-
curses(3), curs_initscr(3), curs_scr_dump(3).
