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

Declare a character array. In each location of the array, store integer numbers, not characters. Then you just send that.

For example:

char tcp[100];

tcp[0] = 0;
tcp[1] = 0xA;
tcp[2] = 0xB;
tcp[3] = 0xC;
.
.

// Send the character array
write(sock, tcp, sizeof(tcp));
