Hello list,

when using the new SCardControl IFDHandler API v3 we came across a
limitation regarding the send buffer length: In winscard.c there is a check
for the send buffer to be not NULL and have a minimal length of 1 byte. We
believe that it would make also sense for the API v3 to allow a command not
using the send buffer.
I added a patch against winscard.c from pcsclite-1.2.9.beta6 which only
does the length checks for IFDHandler APIv2 drivers!

(See attached file: winscardpatch)
