ScMinidriver - Acquire Context with Smart Card or USB Token

See more ScMinidriver Examples

Initializes communication with the card inserted in the given reader (or a USB token). Reader names can be discovered via the SCard.ListReaders or SCard.FindSmartcards methods. If successful, the Atr and CardName properties will be set. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    const scmd = try chilkat.ScMinidriver.init();
    defer scmd.deinit();

    // Reader names (smart card readers or USB tokens) can be discovered
    // via List Readers or Find Smart Cards
    const reader_name = "Alcor Micro USB Smart Card Reader 0";
    scmd.acquireContext(reader_name) catch {
        std.debug.print("{s}\n", .{try scmd.getLastErrorText(alloc)});
        return;
    };

    // If we are successful, the name of the currently inserted smart card is available:
    const card_name = try scmd.getCardName(alloc);
    std.debug.print("Card name: {s}\n", .{card_name});

    // Also, the ATR of the inserted card is available (you will likely not need the ATR).
    std.debug.print("ATR: {s}\n", .{try scmd.getAtr(alloc)});

    // Also, the maximum number of key containers is readily available:
    std.debug.print("Max number of key containers = {d}\n", .{scmd.getMaxContainers()});

    // Delete the context when finished with the card.
    scmd.deleteContext() catch {
        std.debug.print("{s}\n", .{try scmd.getLastErrorText(alloc)});
    };

    // Sample output:

    // Card name: IDPrime MD T=0
    // ATR: 3B7F96000080318065B0855956FB120FFE829000
    // Max number of key containers = 20
