The AuditQuerySystemPolicy function retrieves system audit policy for one or more audit-policy subcategories.

Syntax

BOOLEAN AuditQuerySystemPolicy(
  [in]  const GUID                *pSubCategoryGuids,
  [in]  ULONG                     dwPolicyCount,
  [out] PAUDIT_POLICY_INFORMATION *ppAuditPolicy
);

Parameters

[in] pSubCategoryGuids

A pointer to an array of GUID values that specify the subcategories for which to query audit policy. For a list of defined audit-policy subcategories, see Auditing Constants.

[in] dwPolicyCount

The number of elements in each of the pSubCategoryGuids and ppAuditPolicy arrays.

[out] ppAuditPolicy

A pointer to a single buffer that contains both an array of pointers to AUDIT_POLICY_INFORMATION structures and the structures themselves. The AUDIT_POLICY_INFORMATION structures specify the system audit policy for the subcategories specified by the pSubCategoryGuids array.

When you have finished using this buffer, free it by calling the AuditFree function.
