sc_file_t 3 opensc 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.
