To download/update the Unicorn Go bindings, run:

    go get -u github.com/unicorn-engine/unicorn/bindings/go

A very basic usage example follows

_(Does not handle most errors for brevity. Please see sample.go for a more hygenic example):_

    package main

    import (
        "fmt"
        uc "github.com/unicorn-engine/unicorn/bindings/go/unicorn"
    )

    func main() {
        mu, _ := uc.NewUnicorn(uc.ARCH_X86, uc.MODE_32)
        // mov eax, 1234
        code := []byte{184, 210, 4, 0, 0}
        mu.MemMap(0x1000, 0x1000)
        mu.MemWrite(0x1000, code)
        if err := mu.Start(0x1000, 0x1000+uint64(len(code))); err != nil {
            panic(err)
        }
        eax, _ := mu.RegRead(uc.X86_REG_EAX)
        fmt.Printf("EAX is now: %d\n", eax)
    }

An example program exercising far more Unicorn functionality and error handling can be found in sample.go.
