The VarInfo struct is
a data structure representing a TI variable. Use the 'Type Conversion Macros'
for accssing these fields. Do not use direct access for a better compatibility.
- var_path: the path of the variable,
- var_name_b: the binary name that is to say as stored in the calculator,
- var_name_t: the real name of the variable that is to say readable
by human people,
- var_type: the type of variable. Can be one of the following value:
TYPE_TEXT, ... See the 'Misc defs' for the complete list of values.
- var_atrb: the attribute of the variable. The variable can be locked,
protected or (exclusive or) archived or nothing.
- var_size: the real size of the variable (size of the data block),
- data: the variable content,
- calc_type: the calculator type: 82...92+. A constant such as TYPE_TI92.
- offset: the number of bytes from the beginning of the file up to
the data block,
- is_folder: defines whether the structure contains information about
a folder entry or a variable entry.

The FileInfo struct
is a data structure representing a TI file. Use the 'Type Conversion Macros'
for accssing these fields. Do not use direct access for a better compatibility.
- filename: the complete name of the file (path, name and extension),
- name: the name of the file with path,
- extension: the extension of the filename,
- file_type: the type of file such as single, group, backup or flash
file,
- calc_type: the type of calculator (82...92+),
num_of_vars: the number of variables contained in the specified file,
- comment: the comment stored in the file,
- data_size: the total size of the data block(s),
var_list: a linked list of VarInfo elements. This list contains informations
about each variable of the file (group file),
- var_info: simply a pointer on the first element of the var_list field.
