NTSTATUS RtlMakeSelfRelativeSD( IN PSECURITY_DESCRIPTOR SecurityDescriptor, IN OUT PSECURITY_DESCRIPTOR SelfRelativeSecurityDescriptor, IN OUT PULONG BufferLength ); Routine Description: Makes a copy of a security descriptor. The produced copy will be in self-relative form. The security descriptor to be copied may be in either absolute or self-relative form. Arguments: SecurityDescriptor - Pointer to a security descriptor. This descriptor will not be modified. SelfRelativeSecurityDescriptor - Pointer to a buffer that will contain the returned self-relative security descriptor. BufferLength - Supplies the length of the buffer. If the supplied buffer is not large enough to hold the self-relative security descriptor, an error will be returned, and this field will return the minimum size required. Return Value: STATUS_BUFFER_TOO_SMALL - The supplied buffer was too small to contain the resultant security descriptor.
