streambuf::streambuf

Protected

streambuf();

streambuf( char* pr, int nLength );

END Protected

Parameters

pr

A pointer to a previously allocated reserve area of length nLength. A NULL value indicates an unbuffered stream.

nLength

The length (in bytes) of the reserve area. A length of 0 indicates an unbuffered stream.

Remarks

The first constructor makes an uninitialized streambuf object. This object is not suitable for use until a setbuf call is made. A derived class constructor usually calls setbuf or uses the second constructor.

The second constructor initializes the streambuf object with the specified reserve area or marks it as unbuffered.
