Or you can use constructor expressions to make this slightly more
elegant, though I retain the assumptions about type sizes:
char *foo1(char* buf){
memcpy(buf, (char[]) { 42 }, 1);
buf += 1;
memcpy(buf, (short[]) { 0xfeed }, 2);
buf += 2;
memcpy(buf, (int[]) { 0x12345678 }, 4);
buf += 4;
memcpy(buf, (int[]) { 0x12345678 }, 4);
buf += 4;
return buf;
}
