Pack a byte buffer into the message buffer. More...

Pack a byte buffer into the message buffer.

Synopsis:

#include "rnr/netmsgs.h"

extern int nmPackBuf(byte_t bufSrc, size_t uCount, byte_t buf[], size_t bufSize, 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]	bufSrc	Source buffer.
	uCount	Number of bytes to copy.
[out]	buf	Output message buffer.
	bufSize	Size of output buffer.
	eEndian	Packing order. See NMEndian_T.

Returns

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