10 C bindings for rocksdb. May be useful as a stable ABI that can be
11 used by programs that keep rocksdb in a shared library, or for
12 a JNI api.
13
14 Does not support:
15 . getters for the option types
16 . custom comparators that implement key shortening
17 . capturing post-write-snapshot
18 . custom iter, db, env, cache implementations using just the C bindings
19
20 Some conventions:
21
22 (1) We expose just opaque struct pointers and functions to clients.
23 This allows us to change internal representations without having to
24 recompile clients.
25
26 (2) For simplicity, there is no equivalent to the Slice type. Instead,
27 the caller has to pass the pointer and length as separate
28 arguments.
29
30 (3) Errors are represented by a null-terminated c string. NULL
31 means no error. All operations that can raise an error are passed
32 a "char** errptr" as the last argument. One of the following must
33 be true on entry:
34 *errptr == NULL
35 *errptr points to a malloc()ed null-terminated error message
36 On success, a leveldb routine leaves *errptr unchanged.
37 On failure, leveldb frees the old value of *errptr and
38 set *errptr to a malloc()ed error message.
39
40 (4) Bools have the type unsigned char (0 == false; rest == true)
41
42 (5) All of the pointer arguments must be non-NULL.
