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<VolumeInfo> KDUpdater::mountedVolumes()
Returns currently mounted volumes as list of the VolumeInfo
objects.
QList<ProcessInfo> KDUpdater::runningProcesses()
Returns a list of currently running processes.
