When a Go function calls a C function, it prepares for the C function to
call back to a Go function. The #cgo nocallback directive may be used to
tell the compiler that these preparations are not necessary.
If the nocallback directive is used and the C function does call back into
Go code, the program will panic.

For example:

	// #cgo nocallback cFunctionName
