Name: printw
|
||
|
|
|
||
|
|
Synopsis:
|
||
|
|
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,...);
|
||
|
|
int vwprintw(WINDOW *win, const char *fmt, va_list varglist);
|
||
|
|
int vw_printw(WINDOW *win, const char *fmt, va_list varglist);
|
||
|
|
|
||
|
|
Description:
|
||
|
|
The printw() functions add a formatted string to the window at
|
||
|
|
the current or specified cursor position. The format strings are
|
||
|
|
the same as used in the standard C library's printf(). (printw()
|
||
|
|
can be used as a drop-in replacement for printf().)
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
All functions return the number of characters printed, or
|
||
|
|
ERR on error.
