The event pointer is an optional output, so if the pointer is non-NULL then we should be writing a value to it (e.g. make_event(N), and checking that the expected value was written in the calling function.

See, for example:

TEST_ASSERT_NOT_EQUAL(nullptr, errcode_ret);
TEST_ASSERT_EQUAL(0, num_calls);
return make_mem(0);
}
void testenqueueMapBuffer() {
cl_bool blocking = CL_TRUE;
cl_map_flags flags = CL_MAP_WRITE;
cl::size_type offset = 0;
cl::size_type size = sizeof(int) * 1024;
cl::Event event_data(make_event(0), false);
cl::Event *event = &event_data;
const cl::vector<cl::Event> *events = nullptr;
cl_int *err = nullptr;
void *ret = nullptr;

clEnqueueMapBuffer_StubWithCallback(
clEnqueueMapBuffer_testenqueueMapBuffer);
ret = enqueueMapBuffer(bufferPool[0], blocking, flags, offset, size, events,
event, err);

I don't have a very strong opinion about this, but it would require less code to pass in some of these values directly vs. assigning them to a variable first.

Suggested change
ret = enqueueMapBuffer(bufferPool[0], blocking, flags, offset, size, events,
event, err);
ret = enqueueMapBuffer(bufferPool[0], CL_TRUE, CL_MAP_WRITE, 0, sizeof(int) * 1024, events,
event, err);


TEST_ASSERT_EQUAL_PTR(make_mem(0), ret);
event_data() = nullptr;
}
} // extern "C"
