imagehlp/tests: Add test for BindImageEx

[Bernhard Reiter]

Still struggling to get my first patch ready to be committed. I've
removed all the typecasts I was able to, fixed variable names, and tried
to initialize variables whereever required, as told by people on
#winehackers.

Having been told on that channel to only post to wine-patches@ after
having the patch reviewed on this list, I'd be grateful for a (hopefully
final) review.

Hi Bernhard,

reiterating what I mentioned on IRC previously i.e. me being clueless
about imagehlp, here are some more generic points.

+static int status_routine_called[14] = {0};

No need to explicitly initialize variables with static storage. Not a
big deal though.

+    char kernel32_path[MAX_PATH] = "";

No point in initializing it here, the variable is initialized later on
anyway. You could potentially check for the return value of
GetSystemDirectoryA instead but that's not necessary (most of the
callers of GetSystemDirectoryA don't check for that).

-    char temp_file[MAX_PATH];
+    char temp_file[MAX_PATH] = "";

Same here.

+static void test_bind_image_ex(void)
+{
+    BOOL ret;
+    HANDLE file;
+    char temp_file[MAX_PATH];
+    DWORD count;
+
+    /* Call with a non-existant file */
+    SetLastError(0xdeadbeef);
+    ret = pBindImageEx(BIND_NO_BOUND_IMPORTS | BIND_NO_UPDATE |
BIND_ALL_IMAGES, temp_file, NULL,
+                       NULL, testing_status_routine);

This one "temp_file" NEEDS to be initialized instead, since you're
passing it as a source argument to BindImageEx() and it can
potentially contain anything, being a stack-allocated variable. You
should probably use an obvious initializer like 'char
temp_file[MAX_PATH] = "notexisting.dll";' or something.
