Pack an signed 64-bit integer into the message buffer. More...

Pack an signed 64-bit integer into the message buffer.

Synopsis:

#include "rnr/netmsgs.h"

extern int nmPackS64(long long val, byte_t buf[], size_t bufSize, NMEndian_T eEndian);

Description:
If the machine architecture only supports 32-bit long longs, then the 4 MSBs are signed extended.

Parameters

[in]	val	Value to pack.
[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.
