|
|
|
5 =====================================
|
|
|

|
|
|
7 Starting with version 1.0.0 libuv follows the `semantic versioning`_
|
|
|
8 scheme. This means that new APIs can be introduced throughout the lifetime of
|
|
|
9 a major release. In this section you'll find all macros and functions that
|
|
|
10 will allow you to write or compile code conditionally, in order to work with
|
|
|
11 multiple libuv versions.

16 Macros
|
|
|
17 ------
|
|
|
18
|
|
|
19 .. c:macro:: UV_VERSION_MAJOR
|
|
|
20
|
|
|
21 libuv version's major number.
|
|
|
22
|
|
|
23 .. c:macro:: UV_VERSION_MINOR
|
|
|
24
|
|
|
25 libuv version's minor number.
|
|
|
26
|
|
|
27 .. c:macro:: UV_VERSION_PATCH
|
|
|
28
|
|
|
29 libuv version's patch number.
|
|
|
30
|
|
|
31 .. c:macro:: UV_VERSION_IS_RELEASE
|
|
|
32
|
|
|
33 Set to 1 to indicate a release version of libuv, 0 for a development
|
|
|
34 snapshot.
|
|
|
35
|
|
|
36 .. c:macro:: UV_VERSION_SUFFIX
|
|
|
37
|
|
|
38 libuv version suffix. Certain development releases such as Release Candidates
|
|
|
39 might have a suffix such as "rc".
|
|
|
40
|
|
|
41 .. c:macro:: UV_VERSION_HEX
|
|
|
42
|
|
|
43 Returns the libuv version packed into a single integer. 8 bits are used for
|
|
|
44 each component, with the patch number stored in the 8 least significant
|
|
|
45 bits. E.g. for libuv 1.2.3 this would be 0x010203.
|
|
|

|
|
47 .. versionadded:: 1.7.0

50 Functions
|
|
|
51 ---------
|
|
|
52
|
|
|
53 .. c:function:: unsigned int uv_version(void)
|
|
|
54
|
|
|
55 Returns :c:macro:`UV_VERSION_HEX`.
|
|
|
56
|
|
|
57 .. c:function:: const char* uv_version_string(void)
|
|
|
58
|
|
|
59 Returns the libuv version number as a string. For non-release versions the
|
|
|
60 version suffix is included.
