           #include <opensc.h>
           void sc_copy_asn1_entry(const struct sc_asn1_entry *src, struct sc_asn1_entry *dest);
       This function copies an array of struct sc_asn1_entry entries pointed
       to be src to dest. The array must be NULL-terminated (that is, the last
       entry must have its name field set to NULL). There must be enough space
       available in dest.
