Return whether mount support is available in eeze.

Use this function to determine whether your Eeze library was compiled with a mount binary available.

Since
  1.1

References EINA_FALSE.

EAPI Eina_Bool eeze_disk_can_unmount | ( | void |  | ) |

Return whether unmount support is available in eeze.

Use this function to determine whether your Eeze library was compiled with an unmount binary available.

Since
  1.1

References EINA_FALSE.

EAPI Eina_Bool eeze_disk_can_eject | ( | void |  | ) |

Create a new disk object from a /sys/ path or /dev/ path.

Parameters

  path | The /sys/ or /dev path of the disk; CANNOT be `NULL`.

Returns
  The new disk object

This function creates a new Eeze_Disk from `path`. Note that this function does the minimal amount of work in order to save memory, and udev info about the disk is not retrieved in this call.

Since
  1.1

Parameters

  mount_point | The mount point of the disk; CANNOT be `NULL`

Returns
  The new disk object

This function creates a new Eeze_Disk from `mount_point`. Note that this function does the minimal amount of work in order to save memory, and udev info about the disk is not retrieved in this call. If the disk is not currently mounted, it must have an entry in /etc/fstab.
