Abnormal Fuzz Driver Example for `curl`

[pvz122]

As is shown in a fuzz driver example of library curl, a main function exists in the code:

CKGFuzzer/example/curl/driver_97.cc

Lines 37 to 42 in bb50d2f

	// Main function for fuzzing
	int main(int argc, char **argv) {
	if (argc < 2) {
	fprintf(stderr, "Usage: %s <input_file>\n", argv[0]);
	return 1;
	}

However, all Libfuzzer drivers are required to use the LLVMFuzzerTestOneInput function as the entry of program. This is an obviously abnormal fuzz driver and can not be built successfully.

As far as I understand, these fuzz driver examples were generated successfully by CKGFuzzer and have passed the build procedure. Then how can they possibly contain such an obvious mistake? Or does it mean that these example drivers are merely intermediate programs and are not 100 percent correct?

I'll appreciate your explanation.

That file seems to be a fuzz driver for AFL. This might because LLM didn't follow the instructions strictly. And have you tried build this file? This file appears to build successfully.

Thanks for your reply. I'm actually trying to run these examples with Libfuzzer. This driver seems correct in syntax, but is not able to be built along with Libfuzzer. I'll just discard this one then.
