.SH DESCRIPTION
This structure describes a file object on a smart card.
It contains the following members:
.TP
.B path
This is the full path to the file, starting at the MF.
.TP
.B type
This is the file type. If can be one of
.BR SC_FILE_TYPE_DF ,
.BR SC_FILE_TYPE_WORKING_EF ", or
.BR SC_FILE_TYPE_INTERNAL_EF .
The latter is used by some cards only, and you normally shouldn't
have to deal with these files.
.TP
.B ef_structure
For elementary files (EFs), this field describes the file's
structure. It can be one of
.IP
.nf
.BR SC_FILE_EF_TRANSPARENT
.BR SC_FILE_EF_LINEAR_FIXED
.BR SC_FILE_EF_LINEAR_FIXED_TLV
.BR SC_FILE_EF_LINEAR_VARIABLE
.BR SC_FILE_EF_LINEAR_VARIABLE_TLV
.BR SC_FILE_EF_CYCLIC
.BR SC_FILE_EF_CYCLIC_TLV
.BR SC_FILE_EF_UNKNOWN
.fi
.TP
.B size
gives the file's size in bytes.
.TP
.B id
gives the file's ID, as a 16bit number.
.TP
.BR record_count ", " record_length
