Subject: [PATCH v3 25/28] khash: name the structs that khash declares
Date: Tue, 16 May 2023 06:34:05 +0000 [thread overview]
Message-ID: <6de1eebfea65c8a66bb7270fc7fb550d25d7d3f6.1684218853.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1525.v3.git.1684218848.gitgitgadget@gmail.com>
From: Elijah Newren <newren@gmail.com>
khash.h lets you instantiate custom hash types that map between two
types. These are defined as a struct, as you might expect, and khash
typedef's that to kh_foo_t. But it declares the struct anonymously,
which doesn't give a name to the struct type itself; there is no
"struct kh_foo". This has two small downsides:
- when using khash, we declare "kh_foo_t *the_foo". This is
unlike our usual naming style, which is "struct kh_foo *the_foo".
- you can't forward-declare a typedef of an unnamed struct type in
C. So we might do something like this in a header file:
struct kh_foo;
struct bar {
struct kh_foo *the_foo;
};
to avoid having to include the header that defines the real
kh_foo. But that doesn't work with the typedef'd name. Without the
"struct" keyword, the compiler doesn't know we mean that kh_foo is
a type.
So let's always give khash structs the name that matches our
conventions ("struct kh_foo" to match "kh_foo_t"). We'll keep doing
the typedef to retain compatibility with existing callers.
