it is even worse then that. if clan is defined as:
struct clan_struct clan[MAX_CLAN];
you will be exceeding the array boundry and writing into the date
right after the the array of clan structs because the array index will
run from 0 -> (MAX_CLAN-1)
BIG BIG OUCHIE.
don't forget, it should be
sprintf(buf+strlen(buf),"%s Company\r\n",clan[i].clan_name);
Copying a buffer into itself can do different things on different
implentations of strings.h on different OS's
if you don't like strlen, sprintf returns the number of chars copied
into the buffer. now if only strcat and strcpy did that :)

You have that right this time.

What is MAX_CLAN and why are you not using 'i' for your accesses?
The way you have it you'll access the same variable every time, and you
forgot to append the string onto itself. You'll just keep overwriting the
string until you get to the last one.

Those errors were really easy to spot, I'm sure a little more work and you
could have found them without trouble.
