*(char**)foo casts foo to a char-pointer-pointer. char-pointers are basically arrays of characters, more commonly referred to as strings. So a char-pointer-pointer is a string-pointer. The * in front of it dereferences the pointer, so it dereferences a char** into a char*.
The +0 is probably a leftover from trying different addresses near it.
