This member is called to set a new memory buffer for the
streambuf object. If both parameters are zero, and no input/output operation has yet taken place on this stream, the stream becomes unbuffered.
The inherited public member function
pubsetbuf calls this overriden protected member function to perform this action.
Parameters
- s
- Pointer to an array of n characters already allocated in memory.
- n
- Length in characters of the buffer pointed by s.
This is an integer value of type streamsize.
Return Value
The function returns the pointer
this.
