Non-member functions

operator>>(std::basic_istream)

 

std::streamsize gcount() const;

Returns the number of characters extracted by the last unformatted input operation.

The following member functions of basic_istream change the value of subsequent gcount() calls:

• move constructor
• swap()
• get()
• getline()
• ignore()
• read()
• readsome()
• operator>>(basic_streambuf*)

The following functions set gcount() to zero:

• constructor
• putback()
• unget()
• peek()

Parameters

(none)

Return value

number of characters extracted by the last unformatted input operation
