[PD] A quick question for C dev - temp file on windows

[Pierre Alexandre Tremblay]

Ok the problem is simple: tcl accepts only path separated with ‘/‘ in windows but sys_bashfilename doesn’t convert the (adequately) created windows separator. So I’ll do a character substitutor.

Objvously the code is free and online so people can have a look or I can post here if that helps

In Windows, the code in C does create a file but when I try to pass it to TCL to open there, like in the amazing ELSE’s pic, I can’t - the inverted backslash are deleted. I tried also, like in else, using open_canvas to no avail.
