Description
BasicMemoryStreamBuf is a simple implementation of a stream buffer for reading and writing from a memory area.
This streambuf only supports unidirectional streams. In other words, the BasicMemoryStreamBuf can be used for the implementation of an istream or an ostream, but not for an iostream.

Member Functions
charsWritten
std::streamsize charsWritten() const;
overflow
virtual int_type overflow(
int_type
);
reset
void reset();
Resets the buffer so that current read and write positions will be set to the beginning of the buffer.
seekoff
virtual pos_type seekoff(
off_type off,
std::ios_base::seekdir way,
std::ios_base::openmode which = std::ios_base::in | std::ios_base::out
);
seekpos
virtual pos_type seekpos(
pos_type pos,
std::ios_base::openmode which = std::ios_base::in | std::ios_base::out
);
sync
virtual int sync();
underflow
virtual int_type underflow();
