Enumeration Type Documentation

anonymous enum

anonymous enum

Disk I/O status codes.

Return values used by disk I/O operations to indicate success or failure conditions.

Note

Values are ordered but shall not be relied upon for numeric comparison unless explicitly documented.

Enumerator
DISK_IO_OK	Operation completed successfully.
DISK_IO_ERR	General I/O error occurred.
DISK_INVALID	Invalid parameter or disk identifier.
DISK_NOT_READY	Disk is not initialized or not ready.
DISK_WRITE_PROTECT	Write operation attempted on protected media.
