\chapter{Fortran Restrictions on \code{shared} and \code{private} Clauses with Common Blocks}
|
|
\fortranspecificstart
|
|
\label{chap:fort_sp_common}
|
|
|
|
When a named common block is specified in a \code{private}, \code{firstprivate},
|
|
or \code{lastprivate} clause of a construct, none of its members may be declared
|
|
in another data-sharing attribute clause on that construct. The following examples
|
|
illustrate this point.
|
|
|
|
The following example is conforming:
|
|
|
|
\fnexample{fort_sp_common}{1f}
|
|
|
|
The following example is also conforming:
|
|
|
|
\fnexample{fort_sp_common}{2f}
|
|
% blue line floater at top of this page for "Fortran, cont."

\begin{figure}[t!]
|
|
\linewitharrows{-1}{dashed}{Fortran (cont.)}{8em}
|
|
\end{figure}
|
|
|
|
The following example is conforming:
|
|
|
|
\fnexample{fort_sp_common}{3f}
|
|
|
|
The following example is non-conforming because \code{x} is a constituent element
|
|
of \code{c}:
|
|
|
|
\fnexample{fort_sp_common}{4f}
|
|
|
|
The following example is non-conforming because a common block may not be declared
|
|
both shared and private:
|
|
|
|
\fnexample{fort_sp_common}{5f}
|
|
