The GetSecurityDescriptorDacl function retrieves a pointer to the discretionary access-control list (ACL) in a specified security descriptor.
| Declaration | The GetSecurityDescriptorDacl function retrieves a pointer to the discretionary access-control list (ACL) in a specified security descriptor.Declare Function GetSecurityDescriptorDacl Lib "advapi32.dll" (pSecurityDescriptor As Byte, lpbDaclPresent As Long, pDacl As Long, lpbDaclDefaulted As Long) As Long
|
| Parameters | [in] Pointer to the SECURITY_DESCRIPTOR structure containing the discretionary ACL. The function retrieves a pointer to it.
[out] Pointer to a value that indicates the presence of a discretionary ACL in the specified security descriptor. If this parameter is TRUE, the security descriptor contains a discretionary ACL, and the remaining output parameters in this function receive valid values. If this parameter is FALSE, the security descriptor does not contain a discretionary ACL, and the remaining output parameters do not receive valid values.
[out] Pointer to a pointer to an ACL structure. If a discretionary ACL exists, the function sets the pointer pointed to by pDacl to the address of the security descriptor's discretionary ACL. If a discretionary ACL does not exist, no value is stored.
If the function stores a NULL value in the pointer pointed to by pDacl, the security descriptor has a NULL discretionary ACL. A NULL discretionary ACL implicitly allows all access to an object.

| Return Values | If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
