Encode Example

ZFileEncode encoder;
encoder.open("encode.z");

int int_array[] = {1, 3, 3};
float float_array[] = {5, 5, 8};
string str_data = "hello libz compress, this is repeat string, this is repeat string";

encoder.write(int_array, sizeof(int_array));
encoder.write(float_array, sizeof(float_array));
encoder.write(str_data.data(), str_data.size());
encoder.close();

Decode Example

ZFileDecode decoder;
decoder.open("encode.z");

int int_array[3];
vector<char> buffer;
decoder.read(buffer);
memcpy(int_array, buffer.data(), buffer.size());

for(int i = 0; i < 3; ++i)
  printf("int_array[%d] = %d\n", int_array[i]);
