對象序列化類庫，MessagePack 的 C 實現發布 1.0.0 版本

MessagePack 的 C 實現發布 1.0.0 版本，下載地址：https://github.com/msgpack/msgpack-c
MessagePack是一個基于二進制高效的對象序列化類庫，可用于跨語言通信。它可以像JSON那樣，在許多種語言之間交換結構對象；但是它比JSON更快速也更輕巧。支持Python、Ruby、Java、C/C++等眾多語言。比Google Protocol Buffers還要快4倍。

示例代碼：

#include <msgpack.h>
#include <stdio.h>

int main(void)
{
    /* msgpack::sbuffer is a simple buffer implementation. */
    msgpack_sbuffer sbuf;
    msgpack_sbuffer_init(&sbuf);

    /* serialize values into the buffer using msgpack_sbuffer_write callback function. */
    msgpack_packer pk;
    msgpack_packer_init(&pk, &sbuf, msgpack_sbuffer_write);

    msgpack_pack_array(&pk, 3);
    msgpack_pack_int(&pk, 1);
    msgpack_pack_true(&pk);
    msgpack_pack_str(&pk, 7);
    msgpack_pack_str_body(&pk, "example", 7);

    /* deserialize the buffer into msgpack_object instance. */
    /* deserialized object is valid during the msgpack_zone instance alive. */
    msgpack_zone mempool;
    msgpack_zone_init(&mempool, 2048);

    msgpack_object deserialized;
    msgpack_unpack(sbuf.data, sbuf.size, NULL, &mempool, &deserialized);

    /* print the deserialized object. */
    msgpack_object_print(stdout, deserialized);
    puts("");

    msgpack_zone_destroy(&mempool);
    msgpack_sbuffer_destroy(&sbuf);

    return 0;
}
