I have an ATL project with proxy-stub support enabled, where can I find the implementation of all the methods in xdlldata.h file?

Question

my generated xdlldta.h file 

#ifdef _MERGE_PROXYSTUB

extern "C" 
{
BOOL WINAPI PrxDllMain(HINSTANCE hInstance, DWORD dwReason, 
    LPVOID lpReserved);
STDAPI PrxDllCanUnloadNow(void);
STDAPI PrxDllGetClassObject(REFCLSID rclsid, REFIID riid, LPVOID* ppv);
STDAPI PrxDllRegisterServer(void);
STDAPI PrxDllUnregisterServer(void);
}

#endif

Here, I do not think that the implementation of these methods is a part of my project, and I want to specifically check the implementation of

BOOL WINAPI PrxDllMain(HINSTANCE hInstance, DWORD dwReason, 
    LPVOID lpReserved);

Where can I find the same? Thanks in advance.

Your xlldata.c defines ENTRY_PREFIX:

#define ENTRY_PREFIX    Prx

and then includes dlldata.c, which is generated by MIDL compiler:

#include "dlldata.c"

The generated dlldata.c file includes SDK rpcproxy.h:

#include <rpcproxy.h>

rpcproxy.h in turn looks at the ENTRY_PREFIX, it actually even has some short syntax help in its header.

This is where PrxDllMain is defined:

/*DllMain saves the DLL module handle for later use by DllRegisterServer */ \
BOOL WINAPI DLLMAIN_ENTRY( \
    HINSTANCE  hinstDLL, \
    DWORD  fdwReason, \
    LPVOID  lpvReserved) \
{ \

DLLMAIN_ENTRY there is:

#define __rpc_macro_expand2(a, b) a##b
#define __rpc_macro_expand(a, b) __rpc_macro_expand2(a,b)
// ...
#define DLLMAIN_ENTRY __rpc_macro_expand(ENTRY_PREFIX, DllMain)
