operator>>(basic_istream<charT, traits>& (*pf)(basic_istream<charT, traits>&));
Effects: None. This extractor does not behave as a formatted input function (as described in [istream.formatted.reqmts]).

operator>>(basic_ios<charT, traits>& (*pf)(basic_ios<charT, traits>&));
Effects: Calls pf(*this). This extractor does not behave as a formatted input function (as described in [istream.formatted.reqmts]).
basic_istream<charT, traits>& operator>>(ios_base& (*pf)(ios_base&));
Effects: Calls pf(*this).309 This extractor does not behave as a formatted input function (as described in [istream.formatted.reqmts]).

basic_istream<char, traits>& operator>>(basic_istream<char, traits>& in, unsigned char* s);
template<class traits>
basic_istream<char, traits>& operator>>(basic_istream<char, traits>& in, signed char* s);
Effects: Behaves like a formatted input member (as described in [istream.formatted.reqmts]) of in. After a sentry object is constructed, operator>> extracts characters and stores them into successive locations of an array whose first element is designated by s. If width() is greater than zero, n is width(). Otherwise n is the number of elements of the largest array of char_type that can store a terminating charT(). n is the maximum number of characters stored.
operator>> then stores a null byte (charT()) in the next position, which may be the first position if no characters were extracted. operator>> then calls width(0).
If the function extracted no characters, it calls setstate(failbit), which may throw ios_base::failure ([iostate.flags]).

basic_istream<char, traits>& operator>>(basic_istream<char, traits>& in, signed char& c);
Effects: Behaves like a formatted input member (as described in [istream.formatted.reqmts]) of in. After a sentry object is constructed a character is extracted from in, if one is available, and stored in c. Otherwise, the function calls in.setstate(failbit).
basic_istream<charT, traits>& operator>>(basic_streambuf<charT, traits>* sb);
Effects: Behaves as an unformatted input function. If sb is null, calls setstate(failbit), which may throw ios_base::failure ([iostate.flags]). After a sentry object is constructed, extracts characters from *this and inserts them in the output sequence controlled by sb. Characters are extracted and inserted until any of the following occurs:
end-of-file occurs on the input sequence;
inserting in the output sequence fails (in which case the character to be inserted is not extracted);
an exception occurs (in which case the exception is caught).
If the function inserts no characters, it calls setstate(failbit), which may throw ios_base::failure ([iostate.flags]). If it inserted no characters because it caught an exception thrown while extracting characters from *this and failbit is on in exceptions() ([iostate.flags]), then the caught exception is rethrown.
