I do not completely follow. SCardGetStatusChange is called by refresh_attributes(sc_reader_t *reader). In this context there is only one reader. When this reader is unplugged in Windows the SCardGetStatusChange returns 8010002E -- SCARD_E_NO_READERS_AVAILABLE. In Linux SCardGetStatusChange returns OK and properly sets a new reader status. Imho both have a reason. Finally it's not so important -- both situations are checked and, according to the results of your tests, nothing special has to be done for Mac. > That > would be very strange for me since at least 1 reader is still > available. > > My sample program is available at [1] if you want to test it on Windows. > > Bye Kind regards, Viktor. > [1] > http://anonscm.debian.org/viewvc/pcsclite/trunk/PCSC/UnitaryTests/SCardGetStatusChange.py?view=markup > _______________________________________________ opensc-devel mailing list opensc-devel@lists.opensc-project.org http://www.opensc-project.org/mailman/listinfo/opensc-devel
