Hi all,
I am using google protocol buffer to transmit complex data structures over
socket. Here is the .proto file:
message MatrixMsg
{
required string msgType = 1;
optional int64 count = 2;
optional string extraInfo = 3;
message TaskMsg
{
required string taskId = 1;
required string user = 2;
required string dir = 3;
required string cmd = 4;
required int64 dataLength = 5;
}
repeated TaskMsg tasks = 4;
}
I serialized a MatrixMsg to string through SerializeAsString(), and the
string length is 500. Now, I want to convert the string to char* in order
to send it through socket. However, when I converted to char* through
string.c_str(), the string got truncated. I printed out the string, and
figured out there are white space in it. How do I get a char* that is
exactly matches the string? Thanks!
