SYSTEM_ALARM_CALLBACK_ACE structure (winnt.h)

  • Article

Not supported.

The SYSTEM_ALARM_CALLBACK_ACE structure is reserved for future use.

Syntax

typedef struct _SYSTEM_ALARM_CALLBACK_ACE {
  ACE_HEADER  Header;
  ACCESS_MASK Mask;
  DWORD       SidStart;
} SYSTEM_ALARM_CALLBACK_ACE, *PSYSTEM_ALARM_CALLBACK_ACE;

Members

Header

ACE_HEADER structure that specifies the size and type of ACE. It also contains flags that control inheritance of the ACE by child objects. The AceType member of the ACE_HEADER structure should be set to SYSTEM_ALARM_CALLBACK_ACE_TYPE.

Mask

Specifies an ACCESS_MASK structure that gives the access rights that cause audit messages to be generated. The SUCCESSFUL_ACCESS_ACE_FLAG and FAILED_ACCESS_ACE_FLAG flags in the AceFlags member of the ACE_HEADER structure indicate whether messages are generated for successful access attempts, unsuccessful access attempts, or both.

SidStart

The first DWORD of a trustee's ACE. This ACE can be appended with application data. When the AuthzAccessCheckCallback function is called, this ACE is passed as the pAce parameter of that function.

Remarks

ACE structures must be aligned on DWORD boundaries. All Windows memory-management functions return DWORD-aligned handles to memory.
