DetourFindFunction
Find the address of a target function by name.
PVOID DetourFindFunction(
_In_ LPCSTR pszModule,
_In_ LPCSTR pszFunction
);pszModule : The path of the DLL or binary in which the function should be found.
pszFunction : The name of the function to be found.
If successful, returns the address of the function pszFunction;
otherwise, returns NULL.
DetourFindFunction tries to retrieve a function pointer for a named
function through the dynamic linking export tables of the named module
and then, if that fails, through debugging symbols using the DbgHelp
APIs if available.
DetourFindFunction uses the DbgHelp APIs to access debug symbols. It
dynamically links to the DbgHelp APIs by dynamically loading
DBGHELP.DLL.
If your program can't find debug symbols that you know are available,
the most likely cause is that system either can't find DBGHELP.DLL or
the version of DBGHELP.DLL loaded by the system is broken. This can
happen on 64-bit machines (X64 and IA64) where the system will often
load a 32-bit version of DBGHELP.DLL even though you have written
64-bit code. Some 32-bit versions of Windows also included a
non-functional DBGHELP.DLL stub.
You can test your version of DBGHELP.DLL by using the SymTest
program from the FindFunc directory.
