FLT_PARAMETERS for IRP_MJ_SET_SECURITY union

Union component used when the MajorFunction field of the FLT_IO_PARAMETER_BLOCK structure for the operation is IRP_MJ_SET_SECURITY.

Syntax

typedef union _FLT_PARAMETERS {
  ...    ;
  struct {
    SECURITY_INFORMATION SecurityInformation;
    PSECURITY_DESCRIPTOR SecurityDescriptor;
  } SetSecurity;
  ...    ;
} FLT_PARAMETERS, *PFLT_PARAMETERS;

Members

• SetSecurity: Structure containing the following members.

• SecurityInformation: Pointer to a SECURITY_INFORMATION value that specifies which security information is to be set in the security descriptor. This value can be one of the following.

  SecurityInformation Value	Meaning
  DACL_SECURITY_INFORMATION	The discretionary access control list (DACL) of the object is being set. Requires WRITE_DAC access.
  GROUP_SECURITY_INFORMATION	The primary group identifier of the object is being set. Requires WRITE_OWNER access.
  OWNER_SECURITY_INFORMATION	The owner identifier of the object is being set. Requires WRITE_OWNER access.

Remarks

The FLT_PARAMETERS structure for IRP_MJ_SET_SECURITY operations contains the parameters for a set-security-information operation represented by a callback data (FLT_CALLBACK_DATA) structure. It is contained in an FLT_IO_PARAMETER_BLOCK structure.

IRP_MJ_SET_SECURITY is an IRP-based operation.
