On the irc channel I was suggested that it might have been a good fit for
my use case
I took a look at it in the manual
I'm perplexed. I don't understand it
How is it supposed to be used ?
The provided example is somewhat contrived, I couldn't understand it anyway.
My use case is basic, really.
I have a scheme wrap around a C library for reading xls files, freexl.
Freexl uses a pointer to a structure tha represents the opened xls file and
Each function writes/reads in the memory region pointed to such pointer.
In the end, it requires to use a function that closes the file AND frees
all the involved structures in memory.
So my idea was that I would have gotten a simple macro, like this
(with-xls-file "path/to/my/xls-file.xls" handler-ptr
and this would have expanded to
(freexl-open "path/to/my/xls-file.xls" handler-ptr)
Do I need dynamic-wind at all ?
