several options:
1. We could let the user specify a directory and just create the files
as solution-... and hope it doesn't conflict with other files.
2. flush() the file, then copy, then fclose() it. (not sure how well that works)
3. trick mkstemp:
char template[] = "/tmp/fileXXXXXX";
int fd = mkstemp(template);
fclose(fd);
//now create the file <template>
