virtual void rofl::cpacket::assign	(	uint8_t *	buf,
		size_t	buflen
	)

inlinevirtual

Overwrites memory area with plain buffer specified. Resizes internal memory as necessary.

Parameters

buf	pointer to start of buffer to be copied
buflen	length of buffer to be copied

Reimplemented from rofl::cmemory.

virtual uint8_t* rofl::cpacket::resize ( size_t len )

inlinevirtual

Resizes allocated memory area by calling C-function realloc().

This method resizes the internal memory area and adjusts all internal parameters accordingly, so that any subsequent calls to

See Also: somem() will yield valid results.

Parameters

len	new length of allocated memory area after resize operation

Exceptions

eMemAllocFailed is thrown when the C-function realloc() fails

Reimplemented from rofl::cmemory.
