| Allocate and return a new empty message block of size span_size mimicking parameters of mb.

## Function Documentation

static ACE_Message_Block* clone_mb_nocopy_size | ( | ACE_Message_Block * | mb,
|  | size_t | span_size |
| ) |  |  | `[static]`

Allocate and return a new empty message block of size span_size mimicking parameters of mb.

This function allocates a new aligned message block using the same allocators and flags as found in mb. The size of the new message block is at least span_size; the size may be adjusted up in order to accomodate alignment requirements and still fit span_size bytes into the aligned buffer.

Parameters:

  | mb | message block whose parameters should be mimicked
  | span_size | size of the new message block (will be adjusted for proper alignment)

Returns:
  an aligned message block with rd_ptr sitting at correct alignment spot, 0 on failure
