32 \fBscanw\fR, \fBwscanw\fR, \fBmvscanw\fR,
33 \fBmvwscanw\fR, \fBvwscanw\fR - convert formatted input from a

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

45 \fBchar *fmt\fR [\fB, arg]\fR \fB...);\fR
47 \fBint vwscanw(WINDOW *win, char *fmt, va_list varglist);\fR
49 The \fBscanw\fR, \fBwscanw\fR and \fBmvscanw\fR routines are analogous to
50 \fBscanf\fR [see \fBscanf\fR(3S)]. The effect of these routines is as though
51 \fBwgetstr\fR were called on the window, and the resulting line used as input
52 for \fBsscanf\fR(3). Fields which do not map to a variable in the \fIfmt\fR
55 The \fBvwscanw\fR routine is similar to \fBvwprintw\fR in that it performs a
56 \fBwscanw\fR using a variable argument list. The third argument is a
57 \fIva\fR_\fIlist\fR, a pointer to a list of arguments, as defined in
60 \fBvwscanw\fR returns \fBERR\fR on failure and an integer equal to the
61 number of fields scanned on success.
63 Applications may use the return value from the \fBscanw\fR, \fBwscanw\fR,
64 \fBmvscanw\fR and \fBmvwscanw\fR routines to determine the number of fields
65 which were mapped in the call.
67 The XSI Curses standard, Issue 4 describes these functions. The function
68 \fBvwscanw\fR is marked TO BE WITHDRAWN, and is to be replaced by a function
69 \fBvw_scanw\fR using the \fB<stdarg.h>\fR interface.
