Nick Wellnhofer updated LUCY-254:
---------------------------------
Description:
On Windows, a file won't be deleted until every open handle on it is closed. So
if a file is deleted and immediately recreated with the same filename, the
creation fails if another process (typically a virus scanner) still has an open
handle on it. The solution is to create temporary files with unique names. I
propose to add the following function to {{OperatingSystem.c}}:
{noformat}
char*
chaz_OS_temp_filename(const char *prefix, const char *ext);
{noformat}
It should simply add a number to the filename which is incremented on every
call to that function.
