Functions

func Blocking

func Blocking(fn *byte, arg0, arg1 uintptr)

func BlockingNoop

func BlockingNoop()

BlockingNoop can be used for benchmarking CGO Trampoline overhead. The C function is empty and returns void.

func BlockingSleep

func BlockingSleep(nanos time.Duration)

BlockingSleep invokes C++ std::thread sleep utilizing the safe CGO trampoline. It is preferable to use time.Sleep in likely all circumstances.

func CGONoop

func CGONoop()

CGONoop can be used for benchmarking CGO overhead. The C function is empty and returns void.

func NonBlocking

func NonBlocking(fn *byte, arg0, arg1 uintptr)

NonBlocking C function fn without going all the way through cgo Be very careful using it. If the C code blocks it can/will lock up your app. Example: NonBlocking((*byte)(C.my_c_func), 0, 0)

void my_c_func(size_t arg0, size_t arg1) {
}

func NonBlockingNoop

func NonBlockingNoop()

NonBlockingNoop can be used for benchmarking Assembly Trampoline/CGO trampoline overhead. The C function is empty and returns void.

func NonBlockingSleep

func NonBlockingSleep(nanos time.Duration)

NonBlockingSleep invokes C++ std::thread sleep using Assembly Trampoline. It is only acceptable to do this after runtime.LockOSThread() and only used when absolutely certain.

WARNING!!! You should probably never use this
