LoaderVerifierGetHash (Compact 7)
3/12/2014
The function returns a hash value for the given file.
Syntax
HRESULT LoaderVerifierGetHash(
__in HANDLE hslauthnFile,
__in_opt LPCWSTR pszHashAlgorithm,
__in_bcount_opt(cbHash) BYTE* pbHash,
__in DWORD cbHash,
__out_opt DWORD* pcbHash,
__deref_opt_out LPWSTR* ppszHashAlgorithm
);
Parameters
- hslauthnFile
[in] Handle to the authentication information obtained by calling LoaderVerifierAuthenticateFile.
- pszHashAlgorithm
[in] Pointer to the algorithm identifier for the hash algorithm that returns the hash value. If this parameter is NULL, the loader uses a default hash algorithm. To retrieve the hash calculated with a specific algorithm, specify the algorithm by using a non-NULL value for the szHashHint parameter in the call to LoaderVerifierAuthenticateFile.
- pbHash
[in] Pointer to a variable that receives the hash value for the file. This parameter can be NULL.
- cbHash
[in] Variable that specifies the size, in bytes, of the buffer that pbHash points to. This parameter is ignored if pbHash is NULL.
- pcbHash
[out] Pointer to a variable that receives the required size of the pbHash buffer, in bytes, when the function exits. This parameter can be NULL if pbHash is not NULL.
- ppszHashAlgorithm
[out] Pointer to a variable that receives the algorithm identifier for the hash algorithm that was used to calculate the hash.
Return Value
The values described in the following table are possible return values. If the function is unsuccessful, it returns a standard error code indicating the cause.
| Value | Description |
|---|---|
S_OK |
The function was successful. |
E_HANDLE |

E_INVALIDARG |
One or more parameters have invalid values. |
E_POINTER |
One or more parameters have invalid pointers. |
E_INSUFFICIENTBUFFER |
The pbHash buffer is too small. |
