Hello Everyone,
I have a use case where I wanted to interpret the "Data" object received as a part of my NWConnection's recv call. I have my interpretation logic in cpp so in swift I extract the pointer to the raw bytes from Data and pass it to cpp as a UnsafeMutableRawPointer.
In cpp it is received as a void * where I typecast it to char * to read data byte by byte before framing a response.
I am able to get the pointer of the bytes by using
// Swift Code
// pContent is the received Data
if let content = pContent, !content.isEmpty {
bytes = content.withUnsafeBytes { rawBufferPointer in
guard let buffer = rawBufferPointer.baseAddress else {
// return with null data.
}
// invoke cpp method to interpret data and trigger response.
}
// Cpp Code
void InterpretResponse (void * pDataPointer, int pDataLength) {
char * data = (char *) pDataPointer;
for (int iterator = 0; iterator < pDataLength; ++iterator )
{
std::cout << data<< std::endl;
data++;
}
}
When I pass this buffer to cpp, I am unable to interpret it properly. Can someone help me out here?
Thanks :)
