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.
