When using cgo, Go must not assume that it owns all details of the process. In particular it needs to coordinate with C in the use of threads and thread-local storage. The runtime package declares a few variables: var ( iscgo bool _cgo_init unsafe.Pointer _cgo_thread_start unsafe.Pointer ) Any package using cgo imports "runtime/cgo", which provides
