func Combine

func Combine(crc1, crc2 uint32, len2 int, poly uint32) (crc3 uint32)

Combine takes crc1 = crc32(data1) and crc2 = crc32(data2) and returns crc3 = crc32(concatenate(data1, data2)). The caller must provide len2 = len(data2), but data1 and data2 are not needed.

The polynomial poly is used. These can be obtained from the standard library package crc (e.g. crc.IEEE or crc.Castagnoli).
