I have a data stream of bytes and I'd like to get array of int32 (from four
bytes).
func convertCharToInt32(buffer string) []uint32 {
const SIZEOF_INT32 = 4
var hh = make([]byte, 2)
var cbuffer = make([]byte, len(buffer)/2)
var hbuffer = make([]uint32, len(cbuffer)/SIZEOF_INT32)
for i := 0; i < 28; i++ {
hh[0] = buffer[i*2]
hh[1] = buffer[i*2+1]
if s, err := strconv.ParseUint(string(hh[:]), 16, 64); err == nil {
cbuffer[i] = byte(s)
}
}
for i := range hbuffer {
hbuffer[i] = uint32(Endian.Uint32(cbuffer[i*SIZEOF_INT32 : (i+1)*
SIZEOF_INT32]))
}
return hbuffer
}
buffer := "83f982d600c1caca7a6"
hbuffer := convertCharToInt32(buffer)
The code above seems to work, but perhaps there is a built-in function in
Go that I've missed or there is a super cool hack that does that in one
instruction?
