Bug ID: 56305
           Summary: CryptEnumProviders doesn't set pdwProvType when
                    szProvName is NULL
           Product: Wine
           Version: 9.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: advapi32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The call like below doesn't changes dwType.

```
DWORD       dwIndex = 0;
DWORD       dwType = -1;
DWORD       cbName = -1;

CryptEnumProviders(dwIndex, NULL, 0, &dwType, NULL, &cbName);
```

At the same time the call like below does change dwType.

```
CryptEnumProviders(dwIndex, NULL, 0, &dwType, "Microsoft Base Cryptographic
Provider v1.0", &cbName);
```

The whole point of this call

```
CryptEnumProviders(dwIndex, NULL, 0, &dwType, NULL, &cbName);
```

is to iterate over all providers looking for a specific dwType.
