Minor bug...but it seems reasonable that one ought to be able to do this:Done.
struct _reent my_reent; _REENT_INIT_PTR(&my_reent);
But it doesn't work because the '->' in the macro has higher precedence than the '&', giving you, effectively &(my_reent->_errno) = ... Instead of what you want: (&my_reent)->_errno = ...
This can be worked around with _REENT_INIT_PTR((&my_reent));
But it would be preferable to change the definition of _REENT_INIT_PTR(var)
from
{ var->_errno = ...
To { (var)->errno = ...
