  <ThreadingSafetyStatement>All public static members of this type are
  probably safe for multithreaded operations within managed code.  (Methods
        which are obviously unsafe are synchronized, such as 
        <see cref="M:Mono.Unix.Native.Syscall.ttyname" />, but any hidden dependencies 
        between e.g.
  <see cref="M:Mono.Unix.Native.Syscall.ttyname" /> and 
  <see cref="M:Mono.Unix.Native.Syscall.read" /> are not protected.)
  No multithreading guarantee is made between managed and unmanaged code.

    <summary>The Syscall wrapper class makes it possible to execute the defined system calls. For more information on any of these system calls, the linux manual system (man) has exhaustive information on each syscall in section two: 'man 2 chdir' (or often <c>chdir</c>(2)) for example would give information related to chdir, including error codes, which are in general not listed here.</summary>
    <remarks>The syscall wrapper follows the posix standard. This means some functionality or flags which are linux specific may not be available. Below is a list of known posix syscall functions and features that are not yet implemented.

            an unprivileged user may not delete or rename
            files of other users in that directory.
            The sticky bit may be
            set by any user on a directory which the user owns or has appropriate
            permissions.

            If mode ISUID (set UID) is set on a directory,
            and the MNT_SUIDDIR option was used in the mount of the file system,
            then the owner of any new files and sub-directories
            created within this directory are set
            to be the same as the owner of that directory.
            If this function is enabled, new directories will inherit
            the bit from their parents.
            Execute bits are removed from
            the file, and it will not be given to root.
            This behavior does not change the
            requirements for the user to be allowed to write the file, but only the eventual
            owner after it has been created.
            Group inheritance is not affected.

            This feature is designed for use on fileservers serving PC users via
            ftp, SAMBA, or netatalk.
            It provides security holes for shell users and as
            such should not be used on shell machines, especially on home directories.
            This option requires the SUIDDIR
            option in the kernel to work.
            Only UFS file systems support this option.
            For more details of the suiddir mount option, see
            <c>mount</c>(8) .

            Writing or changing the owner of a file
            turns off the set-user-id and set-group-id bits
            unless the user is the super-user.
            This makes the system somewhat more secure
            by protecting set-user-id (set-group-id) files
            from remaining set-user-id (set-group-id) if they are modified,
            at the expense of a degree of compatibility.

          <para>
            The
            <c>close</c>()
            system call deletes a descriptor from the per-process object
            reference table.
            If this is the last reference to the underlying object, the
            object will be deactivated.
            For example, on the last close of a file
            the current
            <i>seek</i>
            pointer associated with the file is lost;
            on the last close of a
            <see cref="M:Mono.Unix.Native.Syscall.socket" />(2)
            associated naming information and queued data are discarded;
            on the last close of a file holding an advisory lock
            the lock is released (see further
            <see cref="M:Mono.Unix.Native.Syscall.flock" />(2) ) .
            However, the semantics of System V and
            St -p1003.1-88            dictate that all
            <see cref="M:Mono.Unix.Native.Syscall.fcntl" />(2)
            advisory record locks associated with a file for a given process
            are removed when
            <i>any</i>
            file descriptor for that file is closed by that process.
          </para>
          <para>
            When a process exits,
            all associated file descriptors are freed, but since there is
            a limit on active descriptors per processes, the
            <c>close</c>()
            system call
            is useful when a large quantity of file descriptors are being handled.
          </para>
          <para>
            When a process forks (see
            <see cref="M:Mono.Unix.Native.Syscall.fork" />(2) ) ,
            all descriptors for the new child process reference the same
            objects as they did in the parent before the fork.
            If a new process is then to be run using
            <see cref="M:Mono.Unix.Native.Syscall.execve" />(2) ,
            the process would normally inherit these descriptors.
            Most
            of the descriptors can be rearranged with
            <see cref="M:Mono.Unix.Native.Syscall.dup2" />(2)
            or deleted with
            <c>close</c>()
            before the
            <see cref="M:Mono.Unix.Native.Syscall.execve" />(2)
            is attempted, but if some of these descriptors will still
            be needed if the execve fails, it is necessary to arrange for them
            to be closed if the execve succeeds.
            For this reason, the call
            <c>Li fcntl(d, F_SETFD, FD_CLOEXEC)</c>
            is provided,
            which arranges that a descriptor will be closed after a successful
            execve; the call
            <c>Li fcntl(d, F_SETFD, 0)</c>
            restores the default,
            which is to not close the descriptor.

            causes the file named by

            <paramref name="length" /> 
            bytes in size.
            If the file
            was larger than this size, the extra data
            is lost.
            If the file was smaller than this size,
            it will be extended as if by writing bytes
            with the value zero.
            With

            the file must be open for writing.

            If it cannot avoid caching the data,

            The

            system call
            removes the link named by

            from its directory and decrements the link count of the
            file which was referenced by the link.
            If that decrement reduces the link count of the file
            to zero,
            and no process has the file open, then
            all resources associated with the file are reclaimed.
            If one or more process have the file open when the last link is removed,
            the link is removed, but the removal of the file is delayed until
            all references to it have been closed.
