-@subheading DESCRIPTION:
-
-The @code{open} function establishes a connection between a file and a file 
-descriptor.  The file descriptor is a small integer that is used by I/O 
-functions to reference the file.  The @code{path} argument points to the 
-pathname for the file.
-
-The @code{oflag} argument is the bitwise inclusive OR of the values of 
-symbolic constants.  The programmer must specify exactly one of the following
-three symbols:
-
-@table @b
-@item O_RDONLY
-Open for reading only.
-
-@item O_WRONLY
-Open for writing only.
-
-@item O_RDWR
-Open for reading and writing.
-
-@end table
-
-Any combination of the following symbols may also be used.
-
-@table @b
-@item O_APPEND
-Set the file offset to the end-of-file prior to each write.
-
-@item O_CREAT
-If the file does not exist, allow it to be created.  This flag indicates
-that the @code{mode} argument is present in the call to @code{open}.
-
-@item O_EXCL
-This flag may be used only if O_CREAT is also set.  It causes the call
-to @code{open} to fail if the file already exists.
-
-@item O_NOCTTY
-If @code{path} identifies a terminal, this flag prevents that teminal from
-becoming the controlling terminal for thi9s process.  See Chapter 8 for a
-description of terminal I/O.
-
-@item O_NONBLOCK
-Do no wait for the device or file to be ready or available.  After the file
-is open, the @code{read} and @code{write} calls return immediately.  If the 
-process would be delayed in the read or write opermation, -1 is returned and 
-@code{errno} is set to @code{EAGAIN} instead of blocking the caller.
-
-@item O_TRUNC
-This flag should be used only on ordinary files opened for writing.  It 
-causes the file to be tuncated to zero length..
-
-@end table
-
-Upon successful completion, @code{open} returns a non-negative file 
-descriptor.
