bee is a library that gives a simple and easy-to-use API to access PKCS#11 devices, allowing you to use
the function implemented in a PKCS#11 module.

The library offers a set of C functions which let you write your program in a more readable and elegant
way: you do not need to know all the details of the PKCS#11 standard, the session management is automatically
handled by the library in a transparent way and also you do not need to store a pointer to the functions exported
by the module. Moreover, it also gives an object-oriented abstraction suitable to build binding to host the library
in other (object-oriented) languages.

The following program demonstrate how easy it is to login to a PKCS#11 device and list all the objects stored
inside it using bee.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <bee.h>


int main()
{
    bee b;
    CK_OBJECT_HANDLE key, *search;
    CK_ULONG how_many;
    attrs my_attrs, a;
    int j;

    if (init("/path/to/your/module", "12345", &b) != CKR_OK)
    {
        printf("too bad: cannot init my bee!\n");
        return 1;
    }

    init_attrs(&my_attrs);
    if (find_objects(b, my_attrs, &search, &how_many) != CKR_OK)
    {
        printf("failed while searching for 'foo'\n");
        return 1;
    }

    init_attrs(&a);
    add_attribute(&a, CKA_LABEL, NULL_PTR, 0);

    printf("found %lu object(s)\n", how_many);
    if (how_many > 0)
    {
        for (j = 0; j < how_many; j++)
        {
            printf("%d: ", j);
            if (get_attrs(b, search[j], a) != CKR_OK)
                printf("cannot get label for this object\n");
            else
            {
                printf("%s\n", (CK_CHAR *) a.as[0].pValue);
                free(a.as[0].pValue);
            }

            a.as[0].pValue = NULL_PTR;
            a.as[0].ulValueLen = 0;
        }
    }

    logout(&b);
    return 0;
}
