int vw_printw(WINDOW *win, char *fmt, va_list varglist);

Parameters

fmt

Is a printf() format string.

varglist

Is a pointer to a list of parameters.

win

Is a pointer to the window in which the string is to be written.

Description

The vw_printw() function achieves the same effect as wprintw(3XCURSES) using a variable argument list. The third argument is a va_list, as defined in <stdarg.h>.

Return Values

Upon successful completion, vw_printw() returns OK. Otherwise, it returns ERR.

Errors

No errors are defined.

Usage

The vw_printw() function is preferred over vwprintw(3XCURSES). The use of the vwprintw() and vw_printw() in the same file will not work, due to the requirements to include <varargs.h> and <stdarg.h>, which both contain definitions of va_list.
