RtlUshortByteSwap function

The RtlUshortByteSwap routine reverses the ordering of the two bytes in a 16-bit unsigned integer value.

Syntax

void RtlUshortByteSwap(
   _x
);

Parameters

_x

TBD

Return Value

None

Remarks

For example, if the Source parameter value is 0x1234, the routine returns 0x3412.

A typical use of this routine is to convert a USHORT value from little-endian byte format to big-endian byte format, and vice versa.

Use this routine instead of ntohs or htons.

To reverse the ordering of bytes in a ULONG value, use the RtlUlongByteSwap routine. To reverse ordering of bytes in a ULONGLONG value, use the RtlUlonglongByteSwap routine.
