Unpack an unsigned 64-bit integer from the message buffer. More...

Unpack an unsigned 64-bit integer from the message buffer.

Synopsis:

#include "rnr/netmsgs.h"

extern int nmUnpackU64(byte_t buf[], size_t bufSize, ulonglong_t *pVal, NMEndian_T eEndian);

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

Parameters

[in]	buf	Input message buffer.
	bufSize	Size of input buffer.
[out]	pVal	Pointer to value to unpack (set).
	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.
