// You always want to clear this one to prevent memory leaks but you
// might add some others later.

ACE_NEW_MALLOC_RETURN (nb,
static_cast<ACE_Data_Block*> (
this->data_block_allocator_->malloc (sizeof (ACE_Data_Block))),

// Message block initialization may fail while the construction
// succeds. Since as a matter of policy, ACE may throw no
// exceptions, we have to do a separate check like this.
if (nb != 0 && nb->size () < newsize)
{

this->data_block_allocator_->free (nb); // free ...
errno = ENOMEM;
return 0;
}
// Set new flags minus the mask...
nb->clr_flags (mask | always_clear);
