Thank you for proposing a solution for this issue.
If we fix it in this way, we should also fix the documentation.  Here is the
verbatim copy of the example included by __FSEXT_get_function from fsext.txh:

@example
_read(int fd, void *buf, int len)
@{
  __FSEXT_Function *func = __FSEXT_get_function(fd);
  if (func)
  @{
    int rv;
    if (func(__FSEXT_read, &rv, &fd))  <--- Here is the fault. fd is int instead of va_list.
      return rv;
  @}
  /* rest of read() */
@}
@end example

As can be seen the example reproduces the faulty code identicaly.  If we fix
the code we should fix the documentation and we should document the wrapper
functions too.

Regards,
Juan M. Guerrero
