basic_istream::read
Reads a specified number of characters from the stream and stores them in an array.
This method is potentially unsafe, as it relies on the caller to check that the passed values are correct. Consider using basic_istream::_Read_s instead.
basic_istream<Elem, Tr>& read(
char_type *_Str,
streamsize _Count
);
Parameters
_Str
The array in which to read the characters._Count
The number of characters to read.
Return Value
The stream (*this).
Remarks
The unformatted input function extracts up to count elements and stores them in the array beginning at _Str. Extraction stops early on end of file, in which case the function calls setstate(failbit). In any case, it returns *this.
Example
// basic_istream_read.cpp
// compile with: /EHsc
#include <iostream>
using namespace std;
int main()
{
char c[10];
int count = 5;
cout << "Type 'abcde': ";
// Note: cin::read is potentially unsafe, consider
// using cin::_Read_s instead.
cin.read(&c[0], count);
c[count] = 0;
cout << c << endl;
}
