NAME
sc_file_t - OpenSC file structure

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

type
    This is the file type. It 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 16-bit number.

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