示例1: sizeof
TAO_BEGIN_VERSIONED_NAMESPACE_DECL
/*!
* @brief Allocate and return a new empty message block of size \a span_size
* mimicking parameters of \a mb.
*
* This function allocates a new aligned message block using the same
* allocators and flags as found in \a mb. The size of the new message
* block is at least \a span_size; the size may be adjusted up in order
* to accomodate alignment requirements and still fit \a span_size bytes
* into the aligned buffer.
*
* @param mb message block whose parameters should be mimicked
* @param span_size size of the new message block (will be adjusted for proper
* alignment)
* @return an aligned message block with rd_ptr sitting at correct
* alignment spot, 0 on failure
