Maybe not. In the end, the card should enforce the final say on how the things are, the cache only exists to speed things up. >From usage point of view, after the card has been initialized, the structures >on the card don't change that often, so it is safe to say that the file cache >is mostly used to keep track of the "cwd" and to cache metadata about files in >the memory. In addition to SELECT FILE, responses like 6A82 (File not found) from file-oriented commands should be trapped. Are there reasons why this should not be implemented? -- Martin Paljak http://martin.paljak.pri.ee +3725156495 _______________________________________________ opensc-devel mailing list opensc-devel@lists.opensc-project.org http://www.opensc-project.org/mailman/listinfo/opensc-devel
