SetSecurityDescriptorOwner

The SetSecurityDescriptorOwner function sets the owner information of an absolute-format security descriptor. It replaces any owner information already present in the security descriptor.

BOOL SetSecurityDescriptorOwner(
  PSECURITY_DESCRIPTOR pSecurityDescriptor, // SD
  PSID pOwner,                              // SID for owner
  BOOL bOwnerDefaulted                      // flag for default
);

Parameters

pSecurityDescriptor

[in/out] Pointer to the SECURITY_DESCRIPTOR structure whose owner is set by this function. The function replaces any existing owner with the new owner.

pOwner

[in] Pointer to a SID structure for the security descriptor's new primary owner. The SID structure is referenced by, not copied into, the security descriptor. If this parameter is NULL, the function clears the security descriptor's owner information. This marks the security descriptor as having no owner.

bOwnerDefaulted

[in] Indicates whether the owner information is derived from a default mechanism. If this value is TRUE, it is default information. The function stores this value as the SE_OWNER_DEFAULTED flag in the SECURITY_DESCRIPTOR_CONTROL structure. If this parameter is zero, the SE_OWNER_DEFAULTED flag is cleared.

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.
