To me, the insanity is trying to allocate zero byte

• bjornsing 11y ago
  Agree, but that's not the allocator's sanity though.

  That's because you think of it as a special case, which it isn't. If you want to store a string that's n bytes long, you need to allocate n bytes, so a natural thing to write is, for example dst.len=strlen(src);dst.buf=malloc(dst.len); --it's insanity if you need to add a special case for strings of a specific length.

    A standard C string will never be 0 bytes. There is the zero terminator at the end of the string, so all strings will be at least 1 byte large.

      The example is clearly forgoing the use of standard C strings for a char array tagged with the length.

    You don't have to call malloc directly in the second assignment. If you depend on special handling of null without the "if" on invocation you can have your own function for that.
