Msgpack c++ array into raw binary

msgpack c++ array into raw binary

To encode a C++ array into a raw binary using the MessagePack library, you can use the msgpack::sbuffer class to write the encoded data into a buffer.

Here’s an example code snippet that demonstrates how to do this:

#include <iostream>
#include <msgpack.hpp>

int main() {
// Create an array of integers
int arr[] = {1, 2, 3, 4, 5};

// Encode the array using MessagePack
msgpack::sbuffer buffer;
msgpack::packer<msgpack::sbuffer> packer(&buffer);
for (int i = 0; i < sizeof(arr)/sizeof(arr[0]); ++i) {

// Write the encoded data to a file or send it over the network
// …

return 0;

In this code snippet, we create an array of integers arr, and then we encode it using MessagePack. We first create an msgpack::sbuffer object to hold the encoded data, and then we create a msgpack::packer object that writes the encoded data into the buffer.

We use the pack_array function to specify the size of the array, and then we use a loop to pack each element of the array using the pack function.

Finally, we can write the encoded data to a file or send it over the network, depending on our use case.
