# NAME

`curses_print`, `printw`, `wprintw`, `mvprintw`, `mvwprintw`, `unctrl` —
curses print formatted strings on windows routines

# LIBRARY

Curses Library (libcurses, -lcurses)

# SYNOPSIS

`#include <curses.h>`

int
`printw`(const char *fmt, ...);

int
`wprintw`(WINDOW *win, const char *fmt, ...);

int
`mvprintw`(int y, int x, const char *fmt, ...);

int
`mvwprintw`(WINDOW *win, int y, int x, const char *fmt, ...);

char *
`unctrl`(chtype ch);

# DESCRIPTION

These functions print formatted strings on `stdscr` or on the specified window.

The `printw`() function formats and prints its arguments on `stdscr`. The behavior is deliberately similar to that of printf(3), but, notably, the return value differs.

The `wprintw`() function is the same as the `printw`() function, excepting that the resulting output is printed on the window specified by win.

The `mvprintw`() and `mvwprintw`() functions are the same as the `printw`() and `wprintw`() functions, respectively, excepting that `wmove`() is called to move the cursor to the position specified by y, x before the output is printed on the window.

The `unctrl`() function returns a printable string representation of the character ch. If ch is a control character then it will be converted to the form ^Y.

# RETURN VALUES

Functions returning pointers will return `NULL` if an error is detected. The functions that return an int will return one of the following values:

`OK`
  The function completed successfully.
`ERR`
  An error occurred in the function.
