I'd like to create an iostream that writes data in binary format to a
pre-allocated block of memory. I'm already using array_sink to handle
the 'write to a pre-allocated block of memory' part:
char* my_data = new char;
int i = 15;
float f = 5.1345;
os << i;
os << f;
os << "Hello World!";
os << 'c';
However, all the data written to my_data is in text format (i.e. 15 is
encoded in 2 bytes 0x31 0x35 instead of 4 (assuming 32-bit integers)).
What I'd like is something like file_sink where you specify the mode as
binary. The 'mode' seems to be a Device-level decision (as it is with
basic_file_sink) so I'm guessing array_sink is not what I need afterall.
Does something exist for writing binary data to a block of memory?
