InitializeSecurityDescriptor function

The InitializeSecurityDescriptor function initializes a new security descriptor.

Syntax

BOOL InitializeSecurityDescriptor(
  PSECURITY_DESCRIPTOR pSecurityDescriptor,
  DWORD                dwRevision
);

Parameters

pSecurityDescriptor

A pointer to a SECURITY_DESCRIPTOR structure that the function initializes.

dwRevision

The revision level to assign to the security descriptor. This parameter must be SECURITY_DESCRIPTOR_REVISION.

Return Value

If the function succeeds, the function returns nonzero.

If the function fails, it returns zero. To get extended error information, call GetLastError.

Remarks

The InitializeSecurityDescriptor function initializes a security descriptor in absolute format, rather than self-relative format.

The InitializeSecurityDescriptor function initializes a security descriptor to have no system access control list (SACL), no discretionary access control list (DACL), no owner, no primary group, and all control flags set to FALSE (NULL). Thus, except for its revision level, it is empty.

Examples

For an example that uses this function, see Creating a Security Descriptor for a New Object.
