I'm a newbe in pcsc-lite use and so I need some help.
I'm using pcsc-lite-1.2.9beta7 in an enbedded system; I'm working with a
linux 2.4.21 kernel on ARM device with an ACR38 USB Smart Card reader.
All seems to work correctly but after the first pcscd start there are
three pcscd instances at least, if I make ps on my shell.
During the excution of my application pcscd instances became six or
eight or even more.
Is it normal?
I don't know yet.
Send us the output of "ps auxwww"
Hello,
Sorry for my late, this is my ps result:
PID Uid VmSize Stat Command
1 root 580 S init
2 root SW [keventd]
3 root SWN [ksoftirqd_CPU0]
4 root SW [kswapd]
5 root SW [bdflush]
6 root SW [kupdated]
7 root SW [mtdblockd]
8 root SW [rpciod]
24 root 568 S /sbin/syslogd -C -m 30
28 root 656 S /usr/sbin/inetd

63 root 564 S /sbin/getty -L ttyS2 9600 vt100
64 root 748 S -sh
68 root 1496 S pcscd start
69 root 1496 S pcscd start
70 root 1496 S pcscd start
467 root 6224 S ./MDC0.9.9.4
468 root 1496 S pcscd start
469 root 1496 S pcscd start
472 root 1496 S pcscd start
474 root 1496 S pcscd start
479 root 572 R ps
I'm using busybox and so ps have no differeces from ps auxwww.
MDC is my application; the first four pcscd instances (PID 50,68,69,70)
come from the first start.
I can also add that I've noted that there is a new pcscd instance every
time I use "SCardEstablishContext".
When I call SCardReleaseContext in my application, pcscd start instance
isn't released.
Thanks for your help.
Carlo L.
