SC_APP_INFO_T(3)

NAME
sc_app_info_t - OpenSC application structure

SYNOPSIS

#include <opensc.h>
#define SC_MAX_AID_SIZE            16
typedef struct sc_app_info {
	unsigned char aid[SC_MAX_AID_SIZE];
	size_t aid_len;
	char *label;
	sc_path_t path;
	unsigned char *ddo;
	size_t ddo_len;
	const char *desc;
	int rec_nr;
} sc_app_info_t;

DESCRIPTION

This structure describes a smart card application. It contains the following members:

aid The applications's AID. An AID uniquely identifies an application, and consists of an RID (a 5-byte "Registered Application Provider Identifier") and a PIX, which identifies an application by that provider. For example, the RID for PKCS#15 consists of the bytes A0 00 00 00 63, and the PIX is the string "PKCS-15". Thus, the AID of a PKCS#15 application on a smart card is A0 00 00 00 63 50 4B 43 53 2D 31.

aid_len
    The length of the AID in bytes.

label
    A UTF-8 string describing the application.

path
    The application's full path on the card, starting at the MF.

ddo

ddo_len

desc
    A description of the application, if available.

rec_nr
    If the EF(DIR) file is record-structured, this has the record number in which this application is stored. Otherwise, this is -1.
