The bytebuffer class can be used to store binary data of arbitrary length.
It is generally more efficient to reuse the same bytebuffer over and over than to allocate a new one for each operation.
bytebuffer::bytebuffer | ( | ) |
Creates an instance of the bytebuffer class with default initial size and increment parameters.
bytebuffer::bytebuffer | ( | size_t | initialsize | ) |
Creates an instance of the bytebuffer class with the specified "initialsize".
bytebuffer::bytebuffer | ( | unsigned char * | initialcontents, |
size_t | initialsize | ||

Creates an instance of the bytebuffer class. The buffer "initialcontents" will be attached to the instance and used as the initial contents. This buffer should not be freed by the calling program.

|
virtual |
Deletes this instance of the bytebuffer class.

unsigned char* bytebuffer::detachBuffer | ( | ) |
Returns a pointer to the buffer currently stored in the bytebuffer, then resets the bytebuffer such that it will no longer use that buffer.
The calling program must deallocate the buffer returned from this method.

void bytebuffer::setPosition | ( | size_t | pos | ) |
Sets the position in the internal buffer at which the next read or write will occur to "pos". If the position is set beyond the end of the buffer, the buffer will grow but the data between the current end of the buffer and the new position will be undefined.
