Checking if library has been initialized

[aguycalled]

Is there any way (without storing the return value of the init function for future use) to determine whether the library has been correctly initialized?

Thanks.

How about defining a global flag?

std::atomic<bool> g_is_mcl_initialized;
bool is_mcl_initialized() { return g_is_mcl_initialized; }

if (initPairing(...)) {
  g_is_mcl_initialized = true;
}
