Convert 2 bytes into an integer

Question

I receive a port number as 2 bytes (least significant byte first) and I want to convert it into an integer so that I can work with it. I've made this:

char buf[2]; //Where the received bytes are  char port[2];  port[0]=buf[1];   port[1]=buf[0];  int number=0;  number = (*((int *)port)); 

However, there's something wrong because I don't get the correct port number. Any ideas?

Answer 1

I receive a port number as 2 bytes (least significant byte first)

You can then do this:

  int number = buf[0] | buf[1] << 8;
