Not quite. The first sequence of bytes is the prefix
(NUL-terminated). The next two bytes is the count of strings in the
list, and the rest of the bytes are the actual strings, separated with
the NUL character. So the following (untested) code would access the
list:
Char* prefix = MemHandleLock(rsrc);
UInt16 count;
MemMove(&count, prefix + StrLen(prefix) + 1, sizeof(UInt16));
Char** strings = new Char*[count];
Char* tmp = prefix + StrLen(prefix) + 1 + sizeof(UInt16);
for (Int16 i = 0; i < count; ++i) {
strings[i] = tmp;
tmp += StrLen(tmp) + 1;
}
