nmUnpackP64

Unpack a 64-bit pointer from the message buffer. More...

Unpack a 64-bit pointer from the message buffer.

Synopsis:

#include "rnr/netmsgs.h"

extern int nmUnpackP64(byte_t buf[], size_t bufSize, void *pVal, NMEndian_T eEndian);

Description:
If the machine architecture only supports 32-bit pointers, then the 4 MSBs are padded with 0's.

Note

Pointer is always unpacked in native byte order.

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.
