I'd like to know if there are any functions in Wine for changing the function pointer values in a DLL's (or, for that matter, an executable's) import table at the time it is loaded.

For exactly what purpose?
If you want to snoop those calls, we already have mechanisms for this in place.

I'm not the original poster, but I'd like to hear more about this.

Not sure what you mean by "snoop"; I want to alter some functions (CreateFile, ReadFile, WriteFile, and DeviceIoControl) in a particular DLL so that they are rerouted to libusb, for example.

Might not be easy.
You have to add yourself to dlls/ntdll/file.c
NtCreateFile, NtWriteFile, NtReadFile ...

Last time I suggested that people were not happy, to say the least.
What I had in mind is writing my own implementation of CreateFile and the like, that deal with those functions, and call wine's own CreateFile and family as necessary.
It's definitely possible, I was just wondering if wine has any built-in mechanisms for patching DLL imports.

No it doesn't.
