Linux Programming Interface: Chapter 4

The three standard file descriptor's are opened on the program's behalf by the [blank_start]______[blank_end]

The O_CREAT flag to open(2) can be used in conjunction with [blank_start]______[blank_end] flag to create a file exclusively (atomically).

The [blank_start]_____[blank_end] flag to open(2) prevents dereferencing symbolic links and its absence is the cause of some vulnerabilities in privileged programs.

When file descriptors are open in a program and a fork(2) and exec(2) happen before closing them - the descriptors can end up being passed to a new program. The [blank_start]_____[blank_end] flag to open(2) closes them for you.

The [blank_start]____[blank_end] is a directory in the proc filesystem which contains information about each file descriptor opened by a program.

The two size types in the function prototype translate to what standard C types (in order of appearance)?

Which of the following flags to open(2) are not a part of the Single UNIX Specification?

The creat(2) system call is equivalent to this open(2) system call

During which system calls does the kernel set the file offset or file pointer?

During which system calls does the kernel update a pointer called the file offset or file pointer.

With file holes the file system doesn’t allocate any disk blocks for a hole until, at some later point, data is written into it

The return value from a successful lseek() is a?

Writing to a file hole performs what action?
