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/")

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.

References EAPI, and eina_stringshare_add().

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

References EAPI, eina_list_append(), and eina_stringshare_add().

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".

References EAPI, and eina_stringshare_add().

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".

References EAPI, and eina_stringshare_add().

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.

References EAPI, and eina_stringshare_add().

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

References EAPI, and eina_stringshare_add().

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

References EAPI, and eina_stringshare_add().
