1 /*
2 xmalloc - a safe malloc
4 Use this function instead of malloc whenever you don't intend to check
5 the return value yourself, for instance because you don't have a good
6 way to handle a zero return value.
8 Typically, Wine's own memory requests should be handled by this function,
9 while the clients should use malloc directly (and Wine should return an
10 error to the client if allocation fails).
