How to get the original function address (addr_pri.h , addr_any.h )
How to replace the original function with stub function (stub.h )
Supported operating systems:
Supported hardware platform:
Supported compiler:
Support function type:
Description of the unit test
Can't stub the exit function, the compiler has made special optimizations.
Can't stub pure virtual functions, pure virtual functions not have the address.
Can't stub lambda functions, lambda functions not get the address.(You can try to use addr_any.h api.)
Can't stub static functions, static function address is not visible.(You can try to use addr_any.h api.)

Stub stub
stub.set(addr, addr_stub)
stub.reset(addr)
