SYNOPSIS

  Functions
EAPI Eina_List * eeze_udev_find_similar_from_syspath (const char *syspath)
Returns a stringshared list of all syspaths that are (or should be) the same device as the device pointed at by syspath.
EAPI Eina_List * eeze_udev_find_unlisted_similar (Eina_List *list)
Updates a list of all syspaths that are (or should be) the same device.
EAPI Eina_List * eeze_udev_find_by_sysattr (const char *sysattr, const char *value)
Find a list of devices by a sysattr (and, optionally, a value of that sysattr).
EAPI Eina_List * eeze_udev_find_by_type (Eeze_Udev_Type type, const char *name)
Find devices using an Eeze_Udev_Type and/or a name.
EAPI Eina_List * eeze_udev_find_by_filter (const char *subsystem, const char *type, const char *name)
A more advanced find, allows finds using udev properties.
EAPI Eina_List * eeze_udev_find_by_subsystem_sysname (const char *subsystem, const char *sysname)
A more advanced find, allows finds using udev subsystem and sysname.

Detailed Description

These are functions which find/supplement lists of devices.

Function Documentation

  EAPI Eina_List* eeze_udev_find_similar_from_syspath (const char * syspath)

Returns a stringshared list of all syspaths that are (or should be) the same device as the device pointed at by syspath.

Parameters
    syspath The syspath of the device to find matches for

Returns
    All devices which are the same as the one passed

References EINA_LIST_FOREACH, eina_list_prepend(), and eina_stringshare_add().

  EAPI Eina_List* eeze_udev_find_unlisted_similar (Eina_List * list)

Updates a list of all syspaths that are (or should be) the same device.

Parameters
    list The list of devices to update

Returns
    The updated list

This function will update list to include all devices matching devices with syspaths currently stored in list. All strings are stringshared.

Note
    This is an expensive call, do not use it unless you must.

References EINA_LIST_FOREACH.

  EAPI Eina_List* eeze_udev_find_by_sysattr (const char * sysattr, const char * value)

Find a list of devices by a sysattr (and, optionally, a value of that sysattr).

Parameters
    sysattr The attribute to find
    value Optional: the value that the attribute should have

Returns
    A stringshared list of the devices found with the attribute

References eina_list_append(), and eina_stringshare_add().

  EAPI Eina_List* eeze_udev_find_by_type (Eeze_Udev_Type type, const char * name)

Find devices using an Eeze_Udev_Type and/or a name.

Parameters
    type An Eeze_Udev_Type or 0
    name A filter for the device name or NULL

Returns
    A stringshared Eina_List of matched devices or NULL on failure

Return a list of syspaths (/sys/$syspath) for matching udev devices.

  EAPI Eina_List* eeze_udev_find_by_filter (const char * subsystem, const char * type, const char * name)

A more advanced find, allows finds using udev properties.

Parameters
    subsystem The udev subsystem to filter by, or NULL
    type 'ID_INPUT_KEY', 'ID_INPUT_MOUSE', 'ID_INPUT_TOUCHPAD', NULL, etc
    name A filter for the device name, or NULL

Returns
    A stringshared Eina_List* of matched devices or NULL on failure

Return a list of syspaths (/sys/$syspath) for matching udev devices. Requires at least one filter.

References eina_list_append(), and eina_stringshare_add().

  EAPI Eina_List* eeze_udev_find_by_subsystem_sysname (const char * subsystem, const char * sysname)

A more advanced find, allows finds using udev subsystem and sysname.

Parameters
    subsystem The udev subsystem to filter by, or NULL
    sysname A filter for the device name, or NULL

Returns
    A stringshared Eina_List* of matched devices or NULL on failure

    A stringshared list of the devices found
