Open Call Arguments
- The pathname to the file,
- The kind of access requested on the file (read, write, append etc.),
- The initial file permission is requested using the third argument called mode. This argument is relevant only when a new file is being created.
After using the file, the process should close the file using close call, which takes the file descriptor of the file to be closed. Some filesystems include a disposition to permit releasing the file.
Some computer languages include run-time libraries which include additional functionality for particular filesystems. The open (or some auxiliary routine) may include specifications for key size, record size, connection speed. Some open routines include specification of the program code to be executed in the event of an error.
