C Error Checking Function (Not really homework, but don't say I said it wasn't)
For my systems programming class we're doing a lot of programming in C and are required to error check most functions as we are currently learning to program with pthreads.

The reason I say this is not really homework, is that it is far above and beyond what is expected for this class. Simply checking each function individually is more than satisfactory. I just feel this is a time-consuming and messy method and hope for a neater solution.

I was wondering if anyone could show me how to write a function that takes any C function as a parameter, followed by all the required parameters for that function, along with a desired return value (in this case the correct one), and performs the following.

    if(function_name(param1, param2, ...) != desired_return_value) {
        fprintf(stderr, "program_name: function_name() failed\n");
        perror("function_name(): ");
    }

Is this possible? It's hardly required by our course, but it just irks me that virtually ever function I write has to have 4 lines of code to error check it. It makes it bloody hard to read.

Even some other suggestions would be good. I'm just trying to increase readability, so if this is totally the wrong direction, some correct direction would be much appreciated.
