InitializeAcl

The InitializeAcl function creates a new ACL structure. An ACL is an access-control list.

Declaration Declare Function InitializeAcl Lib "advapi32.dll" (pAcl As Byte, ByVal nAclLength As Long, ByVal dwAclRevision As Long) As Long
Parameters
  • pAcl
[out] Pointer to an ACL structure initialized by this function.
  • nAclLength
[in] Specifies the length, in bytes, of the buffer pointed to by the pAcl parameter. This value must be large enough to contain the ACL header and all of the access-control entries (ACEs) to be stored in the ACL. See the following Remarks section for more information about calculating the size of an ACL.
  • dwAclRevision
[in] Specifies the revision level of the ACL being created.
Windows NT 4.0 and earlier: This value must be ACL_REVISION.
Windows 2000: This value can be ACL_REVISION or ACL_REVISION_DS. Use ACL_REVISION_DS if the ACL supports object-specific ACEs.
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.
