man sc_file_t (Fonctions bibliothèques) - OpenSC file structure

NAME

sc_file_t - OpenSC file structure

#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;

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.
