Unpack a byte buffer from the message buffer. More...

Unpack a byte buffer from the message buffer.

Synopsis:

#include "rnr/netmsgs.h"

extern int nmUnpackBuf(byte_t buf[], size_t bufSize, byte_t bufDst[], size_t uCount, NMEndian_T eEndian);

Description:
The source and message buffer memory areas can overlap.

Note

The buffer is always packed in sequential order ignoring the byte order parameter.

Parameters

[in]	buf	Input message buffer.
	bufSize	Size of input buffer.
[out]	bufDst	Destination output buffer.
	uCount	Number of bytes to copy.
	eEndian	Unpacking order. See NMEndian_T.

Returns

On success, returns the number of bytes unpacked. On error, the appropriate negated netmsgs error code ( < 0) is returned.
