.SH DESCRIPTION
|
||
|
.LP
|
||
|
The \fIvfwscanf\fP(), \fIvswscanf\fP(), and \fIvwscanf\fP() functions
|
||
|
shall be equivalent to the \fIfwscanf\fP(), \fIswscanf\fP(), and \fIwscanf\fP()
|
||
|
functions, respectively, except that instead of being called with
|
||
|
a variable number
|
||
|
of arguments, they are called with an argument list as defined in
|
||
|
the \fI<stdarg.h>\fP header. These functions shall not invoke the
|
||
|
\fIva_end\fP macro. As these
|
||
|
functions invoke the \fIva_arg\fP macro, the value of \fIap\fP after
|
||
|
the return is unspecified.
|
||
|
.SH RETURN VALUE
|
||
|
.LP
|
||
|
Refer to \fIfwscanf\fP() .
|
||
|
.SH ERRORS
|
||
|
.LP
|
||
|
Refer to \fIfwscanf\fP() .
|

\fIThe following sections are informative.\fP
|
||
|
.SH EXAMPLES
|
||
|
.LP
|
||
|
None.
|
||
|
.SH APPLICATION USAGE
|
||
|
.LP
|
||
|
Applications using these functions should call \fIva_end\fP( \fIap\fP)
|
||
|
afterwards to clean up.
|
