The static variable f is declared inside the lazilyLoadAndInvoke function, which means it will be reinitialized every time the function is called. This could lead to incorrect behavior as the function is expected to load the driver entry point only once.

The declaration of funcName in driver_api.h uses decltype(::funcName)*, while in driver_api.cpp it uses decltype(::funcName)* f. Ensure that the declaration and definition are consistent to avoid potential issues.
