The fcntl.h> header shall define the following symbolic constant used for the fcntl() file descriptor flags, which shall be suitable for use in #if preprocessing. The fcntl.h> header defines the following requests and arguments for use by the functions fcntl() and F_GETFL: Get file status flags and file access modes.

The fcntl.h is a header file defined by the POSIX standard. It accompanies the fcntl() system call and provides symbolic constants (read "macro.
