Question

Could someone please help and tell me how to use protocol buffers. Actually I want to exchange data through sockets between a program running on unix and anoother running on windows in order to run simulation studies.

The programs that use sockets to exchange data, are written in C/C++ and I would be glad if somneone could help me to use protocol buffers in order to exchange data in the form of :

struct snd_data{
    char *var="temp";
    int var1=1;
    float var2;
    double var2;
}

I tried several ways, but still data are not exchanged correctly. Any help would be very appreciated

Thanks for your help,

You start by defining your message in a .proto file:

package foo;

message snd_data {
  required string var= 1;
  required int32 var1 = 2;
  optional float var2 = 3;
  optional double var3 = 4;
}

(I guess the float and double actually are different variables…)

Then you compile it using protoc and then you have code implementing your buffer.
