.SH NAME
|
||
|
|
\fBcurs_scanw\fR: \fBscanw\fR, \fBwscanw\fR, \fBmvscanw\fR,
|
||
|
|
\fBmvwscanw\fR, \fBvwscanw\fR - convert formatted input from a
|
||
|
|
\fBncurses\fR widow
|
||
|
|
.SH SYNOPSIS
|
||
|
|
\fB#include <ncurses.h>\fR
|
||
|
|
|
||
|
|
\fBint scanw(char *fmt\fR [\fB, arg\fR] \fB...);\fR
|
||

|

\fBint wscanw(WINDOW *win, char *fmt\fR [\fB, arg\fR] \fB...);\fR
|

.br
|
||
|
|
\fBint mvscanw(int y, int x, char *fmt\fR [\fB, arg\fR] \fB...);\fR
|
||
|
|
.br
|
||
|
|
\fBint mvwscanw(WINDOW *win, int y, int x,
|
||
|
|
char *fmt\fR [\fB, arg]\fR \fB...);\fR
|

\fBint vwscanw(WINDOW *win, char *fmt, va_list varglist);\fR
|
||
|

.SH DESCRIPTION
|
||
|
|
The \fBscanw\fR, \fBwscanw\fR and \fBmvscanw\fR routines are analogous to
|
||
|
|
\fBscanf\fR [see \fBscanf\fR(3S)]. The effect of these routines is as though
|
||
|
|
\fBwgetstr\fR were called on the window, and the resulting line used as input
|
||
|
|
for \fBsscanf\fR(3). Fields which do not map to a variable in the \fIfmt\fR
|
||
|
|
field are lost.
|
||
|
|
|
||
|
|
The \fBvwscanw\fR routine is similar to \fBvwprintw\fR in that it performs a
|
||
|
|
\fBwscanw\fR using a variable argument list. The third argument is a
|
||
|
|
\fIva\fR_\fIlist\fR, a pointer to a list of arguments, as defined in
|
||
|
|
\fB<varargs.h>\fR.
|
||
|
|
.SH RETURN VALUE
|
||
|
|
\fBvwscanw\fR returns \fBERR\fR on failure and an integer equal to the
|
||
|
|
number of fields scanned on success.
|
||
|
|
|
||
|
|
Applications may use the return value from the \fBscanw\fR, \fBwscanw\fR,
|
||
|
|
\fBmvscanw\fR and \fBmvwscanw\fR routines to determine the number of fields
|
||
|
|
which were mapped in the call.
