The first 16 sectors of the file system are empty and reserved for other uses. The rest begins with a volume descriptor set (a header block which describes...

an operating system can reference through a file descriptor. Once present, this correlation between the file and the memory space permits applications to...

counter-intuitive. All fcntl locks associated with a file for a given process are removed when any file descriptor for that file is closed by that process, even if a...

achieved using file I/O, with the target identified by a file descriptor. The select and poll system calls allow a set of file descriptors to be monitored...

The file descriptor for standard output is 1 (one); the POSIX <unistd.h> definition is STDOUT_FILENO; the corresponding C <stdio.h> variable is FILE* stdout;...
