Function Documentation

EAPI const char* eeze_udev_devpath_get_syspath ( const char *  devpath  ) 

Get the syspath of a device from the /dev/ path.

Parameters:
devpath The /dev/ path of the device
Returns:
A stringshared char* which corresponds to the /sys/ path of the device or NULL on failure

Takes "/dev/path" and returns the corresponding /sys/ path (without the "/sys/")

Referenced by eeze_disk_new(), and eeze_disk_new_from_mount().

EAPI const char* eeze_udev_syspath_get_devname ( const char *  syspath  ) 

Get the /dev/ name from the /sys/ path.

Parameters:
syspath The /sys/ path with or without the /sys/
Returns:
A stringshared char* of the device name without the /dev/ path, or NULL on failure

Takes /sys/$PATH and turns it into the corresponding /dev/x/"y".

EAPI const char* eeze_udev_syspath_get_devpath ( const char *  syspath  ) 

Get the /dev/ path from the /sys/ path.

Parameters:
syspath The /sys/ path with or without the /sys/
Returns:
A stringshared char* with the /dev/ path or NULL on failure

Takes /sys/$PATH and turns it into the corresponding "/dev/x/y".

EAPI const char* eeze_udev_syspath_get_parent ( const char *  syspath  ) 

Find the root device of a device from its syspath.

Parameters:
syspath The syspath of a device, with or without "/sys/"
Returns:
The syspath of the parent device

Return a stringshared syspath (/sys/$syspath) for the parent device.

EAPI Eina_List* eeze_udev_syspath_get_parents ( const char *  syspath  ) 

Returns a list of all parent device syspaths for syspath.

Parameters:
syspath The device to find parents of
Returns:
A stringshared list of the parent devices of syspath
EAPI const char* eeze_udev_syspath_get_property ( const char *  syspath,
const char *  property 
)

Get the property value of a device from the /sys/ path.

Parameters:
syspath The /sys/ path with or without the /sys/
property The property to get; full list of these is a FIXME
Returns:
A stringshared char* with the property or NULL on failure
EAPI const char* eeze_udev_syspath_get_subsystem ( const char *  syspath  ) 

Get the subsystem of a device from the /sys/ path.

Parameters:
syspath The /sys/ path with or without the /sys/
Returns:
A stringshared char* with the subsystem of the device or NULL on failure

Takes /sys/$PATH and returns the corresponding device subsystem, such as "input" for keyboards/mice.

EAPI const char* eeze_udev_syspath_get_sysattr ( const char *  syspath,
const char *  sysattr 
)

Get the sysattr value of a device from the /sys/ path.

Parameters:
syspath The /sys/ path with or without the /sys/
sysattr The sysattr to get; full list of these is a FIXME
Returns:
A stringshared char* with the sysattr or NULL on failure
EAPI Eina_Bool eeze_udev_syspath_is_joystick ( const char *  syspath  ) 

Checks whether the device is a joystick.

Parameters:
syspath The /sys/ path with or without the /sys/
Returns:
If true, the device is a joystick
Since:
1.7
EAPI Eina_Bool eeze_udev_syspath_is_kbd ( const char *  syspath  ) 

Checks whether the device is a keyboard.

Parameters:
syspath The /sys/ path with or without the /sys/

If true, the device is a keyboard
EAPI Eina_Bool eeze_udev_syspath_is_mouse ( const char *  syspath  )
