function byteTableToQword(Table) : Number

Converts a table of bytes to a 64-bit qword (integer).

Function Parameters

Parameter Type Description
Table Table A table containing the bytes to convert (least significant byte first).

Returns

Number — The resulting 64-bit qword (integer).

Explanation

The function takes a table of bytes (e.g., {0x88, 0x77, 0x66, 0x55, 0x44, 0x33, 0x22, 0x11}) and combines them into a single 64-bit value. The first element is the least significant byte (little-endian order).

For example, byteTableToQword({0x88, 0x77, 0x66, 0x55, 0x44, 0x33, 0x22, 0x11}) returns 0x1122334455667788.

Examples

local qword = byteTableToQword({0x88, 0x77, 0x66, 0x55, 0x44, 0x33, 0x22, 0x11})
print(string.format("0x%X", qword)) -- Output: 0x1122334455667788
