Enumeration Type Documentation

◆ disk_type_t

enum disk_type_t

Disk type enumeration.

The disk type is used to identify the type of 64DD disk. The values correspond to the disk types defined in the 64DD specification. There are 7 disk types, 0 - 6, corresponding to the relative sizes of the RAM area and the ROM area on the disk. The disk type of a particular disk is determined by the size of the writable area needed by the programmer.

Enumerator
DISK_TYPE_0	ROM: Zone 0-2, RAM: Zone 3-8
DISK_TYPE_1	ROM: Zone 0-3, RAM: Zone 4-8
DISK_TYPE_2	ROM: Zone 0-4, RAM: Zone 5-8
DISK_TYPE_3	ROM: Zone 0-5, RAM: Zone 6-8
DISK_TYPE_4	ROM: Zone 0-6, RAM: Zone 7-8
DISK_TYPE_5	ROM: Zone 0-7, RAM: Zone 8
DISK_TYPE_6	ROM: Zone 0-8, RAM: None

Function Documentation

◆ disk_info_load()

disk_err_t disk_info_load	(	path_t *	path,
		disk_info_t *	disk_info )

Loads disk information from the specified path.

This function reads the disk information from the given path and populates the provided disk_info structure with the relevant data.

Parameters

path	A pointer to a path_t structure that specifies the path to the disk.
disk_info	A pointer to a disk_info_t structure where the disk information will be stored.

Returns: A disk_err_t value indicating the success or failure of the operation.
