Spying on API calls made by a program

Is there a way to check what API calls a program is making?

Thanks in advance

If you have a certain few functions in mind, then yes;
You can use detours to inject a DLL into the program and re-direct the functions; then when the calls are made, document it and return the result of the actual function.

If you want to see every system call that the program makes, I'm not sure it can be done.

XfoxX,

It is possible to spy on all API calls an application makes. Search Import address tabble hooking.
