A.14 File Sharing
Dynamic Semantics
It is not specified by the language
whether the same external file can be associated with more than one file
object. If such sharing is supported by the implementation, the following
effects are defined:
Operations on one
text file object do not affect the column, line, and page numbers of
any other file object.
For direct and stream files, the current index
is a property of each file object; an operation on one file object does
not affect the current index of any other file object.
For direct and stream files, the current size of
the file is a property of the external file.
All other effects are identical.
