Format and put the message in the buffer.
If expected size is smaller then LOGGER_MAXLINE, formatted message is written to the static buffer and release_ is set to false. Otherwise, this function allocates a buffer on the heap big enough to hold the message and set release_ to true. In this case caller is responsible for releasing the memory by calling delete [].
expected_sz_ | Expected size of the formatted message |
fmt_ | printf()-like format string |
vap_ | variable argument parameters list |
release_ | [OUT] if true, caller is responsible for memory deallocation. |

Maximum length of the formatted message.
The size is selected based on the maximum number of bytes transmitted through Socketbuf which is 1416. This is at most the bytes dumped with MemDump - (1416/16 + 2) * 74 = 6660. See MemDump.cpp comments for details.
