open - open for reading or writing
Open opens the file name for reading (if mode is 0), writing (if mode is 1) or for both
reading and writing (if mode is 2). Name is the address of a string of ASCII characters
representing a path name, terminated by a null character.
The file is positioned at the beginning (byte 0). The returned file descriptor must be
used for subsequent calls for other input-output functions on the file.
creat(2), read(2), write(2), dup(2), close(2)
The value -1 is returned if the file does not exist, if one of the necessary directories
does not exist or is unreadable, if the file is not readable (resp. writable), or if too
many files are open.
(open = 5.)
