winscard - Getting the "name" of the smartcard for SCardGetCardTypeProviderName() -


in order crypto context cryptacquirecontext(), need know provider name smartcard in slot.

according documentation, scardgetcardtypeprovidername() this, param 2 card name, , can't see how determine non-interactively. documentation/examples i've seen either harcode name or rely on scarduidlgselectcard(), displays ui.

similarly reading around scardlocatecards(), although takes list of smartcard names (for i'm populating scardlistcards(), doesn't seem pass identifies name of smartcard inserted.

i suspect i'm missing obvious, can't see what.

i missing something. scardlocatecards returns part of strucutre atr of smartcard, can used in scardlistcards:

scard_readerstate smartcardstate[maximum_smartcard_readers];  result = scardlocatecards (context, cardslist, smartcardstate, readercount); if (result == scard_s_success) {     int i;     (i = 0; < readercount; i++)     {         if (scard_state_atrmatch & smartcardstate[i].dweventstate) {             break;         }     }      result = scardlistcards (null, smartcardstate[i].rgbatr, null, null, cardname, &count);     if (result == scard_s_success) {         // cardname cryptaquirecontext in cardname     } }

if has better route forward let me know - think way though can see.
