Usage

#include <opensc.h>

typedef struct sc_file {
        struct sc_path    path;
        int               type, ef_structure;
        size_t            size;
        int               id;
        /* record structured files only */
        int               record_length;
        int               record_count;
} sc_file_t;

Overview

This structure describes a file object on a smart card. It contains the following members:

path

This is the full path to the file, starting at the MF.

type

This is the file type. If can be one of SC_FILE_TYPE_DF, SC_FILE_TYPE_WORKING_EF, or SC_FILE_TYPE_INTERNAL_EF. The latter is used by some cards only, and you normally shouldn't have to deal with these files.

ef_structure

For elementary files (EFs), this field describes the file's structure. It can be one of

SC_FILE_EF_TRANSPARENT
SC_FILE_EF_LINEAR_FIXED
SC_FILE_EF_LINEAR_FIXED_TLV
SC_FILE_EF_LINEAR_VARIABLE
SC_FILE_EF_LINEAR_VARIABLE_TLV
SC_FILE_EF_CYCLIC
SC_FILE_EF_CYCLIC_TLV
SC_FILE_EF_UNKNOWN

size

gives the file's size in bytes.

id

gives the file's ID, as a 16bit number.

record_count, record_length

For record structured files, record_count specifies the number of records in the file. For files with fixed length records, record_length contains the record length.
