When passing a Go pointer to a C function the compiler normally ensures
that the Go object lives on the heap. If the C function does not keep
a copy of the Go pointer, and never passes the Go pointer back to Go code,
then this is unnecessary. The #cgo noescape directive may be used to tell
the compiler that no Go pointers escape via the named C function.
If the noescape directive is used and the C function does not handle the
