device_info: Obtain information about an 'adf_device' connection

In adfExplorer: Access and Manipulate Amiga Disk Files

Obtain information about an adf_device connection

Description

A collection of functions to retrieve information about the virtual device, or any volume (file system) available on the device. See examples for usage and results.

Usage

device_type(dev, ...)

## S3 method for class 'adf_device'
device_type(dev, ...)

device_capacity(dev, ...)

## S3 method for class 'adf_device'
device_capacity(dev, ...)

volume_capacity(dev, ...)

## S3 method for class 'adf_device'
volume_capacity(dev, vol = 0L, ...)

volume_name(dev, ...)

volume_name(dev, ...) <- value

## S3 method for class 'adf_device'
volume_name(dev, vol = 0L, ...)

## S3 replacement method for class 'adf_device'
volume_name(dev, vol = 0L, ...) <- value

n_volumes(dev, ...)

## S3 method for class 'adf_device'
n_volumes(dev, ...)

bytes_free(dev, ...)

## S3 method for class 'adf_device'
bytes_free(dev, vol = 0L, ...)

is_bootable(dev, ...)

## S3 method for class 'adf_device'
is_bootable(dev, vol = 0L, ...)

is_fast_file_system(dev, ...)

## S3 method for class 'adf_device'
is_fast_file_system(dev, vol = 0L, ...)

is_international(dev, ...)

## S3 method for class 'adf_device'
is_international(dev, vol = 0L, ...)

is_dircache(dev, ...)

## S3 method for class 'adf_device'
is_dircache(dev, vol = 0L, ...)

is_write_protected(dev, ...)

## S3 method for class 'adf_device'
is_write_protected(dev, ...)

Arguments

dev	The virtual adf device for which information needs to be obtained. It should be of class adf_device which can be created with create_adf_device() or connect_adf().
...	Ignored
vol	Volume index number on the device starting at 0. Default is 0. Note that floppy disks can only have 1 volume installed.
value	Replacement value. In case of volume_name() it can be used to assign a new name to the volume.

Value

Returns the requested information, or an updated copy of dev in case of an assign operation (⁠<-⁠).

Examples

## Open virtual device to demonstrate methods
my_device <- demo_adf(write_protected = FALSE)

device_type(my_device)

device_capacity(my_device) # in bytes

volume_capacity(my_device) # in bytes

n_volumes(my_device) # number of volumes available on device

volume_name(my_device) # name of the volume

volume_name(my_device) <- "new_name" # rename the volume

bytes_free(my_device) # bytes available for writing

is_bootable(my_device) # tests if device is potentially bootable

is_fast_file_system(my_device) # tests if volume uses FFS

is_international(my_device) # tests if file system uses intl mode

is_dircache(my_device) # tests if file system uses dir caching

is_write_protected(my_device) # tests if device is protected against writing

close(my_device)
