NAME
vscanf(), vfscanf(), vsscanf() — formatted input conversion to a varargs argument list, read from stream file
SYNOPSIS
#include <stdio.h>
#include <varargs.h>
int vscanf(const char *format, va_list ap);
int vfscanf(FILE *stream, const char *format, va_list ap);
int vsscanf(char *s, const char *format, va_list ap);
DESCRIPTION
vscanf(),
vfscanf(),
and
vsscanf()
are the same as
scanf(),
fscanf(),
and
sscanf()
respectively, except that
instead of being called with a variable number of arguments,
they are called with an argument list as defined by
varargs(5).
APPLICATION USAGE
vscanf(),
vfscanf()
and
vsscanf()
are thread-safe. These interfaces are not async-cancel-safe.
A cancellation point may occur when a thread is executing
vscanf()
or
vfscanf().
