Thread: char string to long conversion

Hello, I have the following question:

I am trying to fit a long variable into char string and then convert it back to long (need this to send that string over the network)

char cs[4];
long lv1=12345;
long lv2;

memcpy(cs, &lv1, 4);
lv2=(long)(tsC);

printf("lv2: %lu ", lv2);

for some reason this doesn't work

Thanks in advance,
Bill
