How do I send an array of integers over TCP in C?

Question

I\'m lead to believe that write() can only send data buffers of byte (i.e. signed char), so how do I send an array of long integers using the C write()

Answer 1

It would be better to have serialize/de-serialize functionality in your client /server program.

Whenever you want to send data, serialize the data into a byte buffer and send it over TCP with byte count.

When receiving data, de-serialize the data from buffer to your own interpretation .

You can interpret byte buffer in any form as you like. It can contain basic data type, objects etc.

Just make sure to take care of endianess and also alignment stuff.
