which allows some number of bytes to be read from a given file
descriptor. The read function is unaware of file system types, such

upon which the file system is mounted, such as AT Attachment Packet
Interface (ATAPI) disk, Serial-Attached SCSI (SAS) disk, or Serial
Advanced Technology Attachment (SATA) disk. Yet, when the read
function is called for an open file, the data is returned as
