Version-checking macros and functions

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

Macros

UV_VERSION_MAJOR

libuv version’s major number.

UV_VERSION_MINOR

libuv version’s minor number.

UV_VERSION_PATCH

libuv version’s patch number.

UV_VERSION_IS_RELEASE

Set to 1 to indicate a release version of libuv, 0 for a development snapshot.

UV_VERSION_SUFFIX

libuv version suffix. Certain development releases such as Release Candidates might have a suffix such as “rc”.

UV_VERSION_HEX

Returns the libuv version packed into a single integer. 8 bits are used for each component, with the patch number stored in the 8 least significant bits. E.g. for libuv 1.2.3 this would be 0x010203.

New in version 1.7.0.

Functions

unsigned int uv_version(void)

Returns UV_VERSION_HEX.

const char *uv_version_string(void)

Returns the libuv version number as a string. For non-release versions the version suffix is included.
