Detailed Description
Easy device manipulation.
Eeze is a library for manipulating devices through udev with a simple and fast api. It interfaces directly with libudev, avoiding such middleman daemons as udisks/upower or hal, to immediately gather device information the instant it becomes known to the system. This can be used to determine such things as:
- If a cdrom has a disk inserted
- The temperature of a cpu core
- The remaining power left in a battery
- The current power consumption of various parts
- Monitor in realtime the status of peripheral devices Each of the above examples can be performed by using only a single eeze function, as one of the primary focuses of the library is to reduce the complexity of managing devices.
For udev functions, see udev.
Enumeration Type Documentation
| enum Eeze_Udev_Event |
Flags for watch events.
These events are used to specify the events to watch in a Eeze_Udev_Watch. They can be ORed together.
Convenience types to simplify udev access.
These types allow easy access to certain udev device types. They may only be used in specified functions.
