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