Unfortunately, the terms are clumsy as hell - POSIX ends up with "file descriptor" (for numbers) vs. "file description" (for IO channels), which is hard to distinguish when reading and just as hard to distinguish when listening. "Opened file" (as IO channel) vs. "file on disc" (as collection of data that might be accessed via said channels) distinction on top of that also doesn't help, to put it mildly. It's many decades too late to do anything about, unfortunately. Pity the UNIX 101 students... ;-/
Just so I understand this correctly. "file descriptor" - is just what maps to a specific inode. "file description" - is how the file is accessed (position in the file and flags associated to how it was opened) Did I get that correct? -- Steve
