Function Documentation

int KDUpdater::compareVersion(const QString &v1, const QString &v2)

This function compares two version strings v1 and v2 and returns -1, 0 or +1 based on the following rule

Returns 0 if v1 == v2
Returns -1 if v1 < v2
Returns +1 if v1 > v2

The function is very similar to strcmp(), except that it works on version strings.

Example:

KDUpdater::compareVersion("2.0", "2.1"); // Returns -1
KDUpdater::compareVersion("2.1", "2.0"); // Returns +1
KDUpdater::compareVersion("2.0", "2.0"); // Returns 0
KDUpdater::compareVersion("2.1", "2.1"); // Returns 0

KDUpdater::compareVersion("2.0", "2.x"); // Returns 0
KDUpdater::compareVersion("2.x", "2.0"); // Returns 0

KDUpdater::compareVersion("2.0.12.4", "2.1.10.4"); // Returns -1
KDUpdater::compareVersion("2.0.12.x", "2.0.x");    // Returns 0
KDUpdater::compareVersion("2.1.12.x", "2.0.x");    // Returns +1
KDUpdater::compareVersion("2.1.12.x", "2.x");      // Returns 0
KDUpdater::compareVersion("2.x", "2.1.12.x");      // Returns 0

quint64 KDUpdater::installedMemory()

Returns the amount of memory installed on a system.

QList<KDUpdater::VolumeInfo> KDUpdater::mountedVolumes()

Returns currently mounted volumes as list of the VolumeInfo objects.

QList<KDUpdater::ProcessInfo> KDUpdater::runningProcesses()

Returns a list of currently running processes.
