- 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.
