Xavier Del Campo Romero 9e183ec0a6 64-bit support, C11 as requirement and other improvements
- C11 support is required (although only on serializer.c, so the check has
been moved there) since _Alignof is needed.
- Added support for little/big endian 64-bit integers.
- swap16, swap32 and swap64 now cast pointers to (uint8_t *) and (const uint8_t *)
from the argument list so the explicit casts are no longer needed.

Serializer/deserializer library for C11

This library hopes to be useful under certain circumstances where a portable implementation is desired to read/write data streams yet endianness and alignment requirements need to be taken into account e.g.: network protocols, file formats, etc. As the title specifies, only a C11-compliant compiler is required.

Only 8-bit and 16/32/64-bit little-endian and big-endian values are supported. This means no support for bit fields, as some aspects of bit fields are implementation-defined.

Usage

#include <serializer.h>
#include <stdint.h>
#include <stdio.h>

int main()
{
    struct
    {
        uint8_t a;
        uint16_t b;
        uint32_t c;
        uint16_t d;
        uint64_t e;
        uint64_t f;
    } ex;

    static const uint8_t data[] =
    {
        0x01, 0x33, 0xFF, 0xAC, 0xBB, 0xFA, 0xFA, 0xDE, 0xDD,
        0x12, 0x33, 0xFF, 0xAC, 0xBB, 0xFA, 0xFA, 0xDE,
        0x12, 0x33, 0xFF, 0xAC, 0xBB, 0xFA, 0xFA, 0xDE,
    };

    deserialize("1/le2/be4/be2/be8/le8", &ex, sizeof ex, data, sizeof data);
    printf("a=%X, b=%X, c=%X, d=%X, e=%lX, f=%lX\n",
            ex.a, ex.b, ex.c, ex.d, ex.e, ex.f);
    return 0;
}

Output

a=1, b=FF33, c=ACBBFAFA, d=DEDD, e=1233FFACBBFAFADE, f=DEFAFABBACFF3312

TODO

Only deserialization is implemented. Serialization will be implemented in the future.
