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

Write can do what you want it to, but there's some things to be aware of:

1: You may get a partial write that's not on an int boundary, so you have to be prepared to handle that situation

2: If the code needs to be portable, you should convert your array to a specific endianess, or encode the endianess in the message.
