Function Documentation

void msObjectInit	(	MemoryStream *	msp,
		uint8_t *	buffer,
		size_t	size,
		size_t	eos
	)

Memory stream object initialization.

Parameters:

[out]	msp	pointer to the MemoryStream object to be initialized
[in]	buffer	pointer to the memory buffer for the memory stream
[in]	size	total size of the memory stream buffer
[in]	eos	initial End Of Stream offset. Normally you need to put this to zero for RAM buffers or equal to size for ROM streams.
