thread local storage

[Eduardo Rocha]

Hi Janne,

Thanks for your answer. But I need some more informations.
I am writing a User-Level Thread library and I would like
to use variable privatization. In C if I write that line:

  static __thread int var1;

inside a functions, for example, the access to var1 is made
through a level of indirection. Thus I can allocate memory for
private variables for each thread and change a pointer to
the current private variables when a context switch happens.
I would like to do the same with Fortran, but I don't know if it is
possible get the same indirection effect in Fortran as in C. Do
you know?

Sorry about my English, but I am Brazilian and my first
language is not English.

Thanks in advance,

Eduardo Rocha
