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.
