| The <STRONG>printw</STRONG>, <STRONG>wprintw</STRONG>, <STRONG>mvprintw</STRONG> and <STRONG>mvwprintw</STRONG> routines are analogous to |
| <STRONG>printf</STRONG> [see <STRONG>printf(3)</STRONG>]. In effect, the string that would be output by |
| <STRONG>printf</STRONG> is output instead as though <STRONG>waddstr</STRONG> were used on the given win- |
| dow. |
| |
| The <STRONG>vwprintw</STRONG> and <STRONG>wv_printw</STRONG> routines are analogous to <STRONG>vprintf</STRONG> [see |
| <STRONG>printf(3)</STRONG>] and perform a <STRONG>wprintw</STRONG> using a variable argument list. The |
| third argument is a <STRONG>va_list</STRONG>, a pointer to a list of arguments, as de- |
| fined in <STRONG><stdarg.h></STRONG>. |
| |
| |
| </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE> |
| Routines that return an integer return <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> (SVr4 |
| only specifies "an integer value other than <STRONG>ERR</STRONG>") upon successful com- |
| pletion. |
| |
| X/Open defines no error conditions. In this implementation, an error |
| may be returned if it cannot allocate enough memory for the buffer used |
| to format the results. It will return an error if the window pointer |
| is null. |
| |
| Functions with a "mv" prefix first perform a cursor movement using |
| <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if |
| the window pointer is null. |
| |
| |
| </PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE> |
| In this implementation, <STRONG>vw_printw</STRONG> and <STRONG>vwprintw</STRONG> are equivalent, to sup- |
| port legacy applications. However, the latter (<STRONG>vwprintw</STRONG>) is obsolete: |
| |
| <STRONG>o</STRONG> The XSI Curses standard, Issue 4 described these functions. The |
| function <STRONG>vwprintw</STRONG> is marked TO BE WITHDRAWN, and is to be replaced |
| by a function <STRONG>vw_printw</STRONG> using the <STRONG><stdarg.h></STRONG> interface. |
| |
| <STRONG>o</STRONG> The Single Unix Specification, Version 2 states that <STRONG>vw_printw</STRONG> is |
| preferred to <STRONG>vwprintw</STRONG> since the latter requires including |
| <STRONG><varargs.h></STRONG>, which cannot be used in the same file as <STRONG><stdarg.h></STRONG>. |
| This implementation uses <STRONG><stdarg.h></STRONG> for both, because that header |
| is included in <STRONG><curses.h</STRONG>>. |
| |
| <STRONG>o</STRONG> X/Open Curses, Issue 5 (December 2007) marked <STRONG>vwprintw</STRONG> (along with |
| <STRONG>vwscanw</STRONG> and the termcap interface) as withdrawn. |
