Hello Darin!

Hmm.. I looks like it would be easier with the extra pointer.

 KK>>> #include 
 KK>>> #include 

 DM> char* test(char** buf, size_t buflen)

 KK>>> {
 DM>   /* char* tmp = (char*)malloc(80); */
 DM>   /* if(tmp) sprintf(tmp, "test"); */

 DM> char* source = "test";
 DM> if (buflen > strlen(source))
 DM>   sprintf(*buf, source);

 DM>   /* return tmp; */
 DM>   return *buf;
 KK>>> }
 KK>>> int main()
 KK>>> {

 DM> char buf[16];
 DM> printf("%s\n", test(buf, sizeof(buf)));

 KK>>>    fgets(buf, 16, stdin);
 KK>>>    return 0;
 KK>>> }

 DM> No malloc/free's here.

No i see thank you :)
