NAME

sc_file - OpenSC file struct

SYNOPSIS

#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;

DESCRIPTION

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.
