## Description

A GvaInputFile provides metadata about a MAME INP file. It handles both current and historical INP formats.

## Details

### GvaInputFile

    typedef struct _GvaInputFile GvaInputFile;

Contains only private data that should be read and manipulated using the functions below.

### gva_input_file_new ()

    GvaInputFile *      gva_input_file_new                  (const gchar *filename);

Creates a new GvaInputFile for the given `filename`.

`filename` : | path to a MAME INP file
Returns : | a new GvaInputFile

### gva_input_file_read ()

    gboolean            gva_input_file_read                 (GvaInputFile *input_file,
                                                             GError **error);

Reads header information from a MAME INP file. The information is made available through the various accessor functions. If an error occurs while reading, the function returns `FALSE` and sets `error`.

`input_file` : | a GvaInputFile
`error` : | return location for a GError, or `NULL`
Returns : | `TRUE` on success, `FALSE` if an error occurred

### gva_input_file_play_back ()

    GvaProcess *        gva_input_file_play_back            (GvaInputFile *input_file,
                                                             GError **error);

Begins play back of `input_file` and returns the resulting GvaProcess. If an error occurs, it returns `NULL` and sets `error`.

`input_file` : | a GvaInputFile
`error` : | return location for a GError, or `NULL`
Returns : | a new GvaProcess, or `NULL`

### gva_input_file_get_filename ()

    const gchar *       gva_input_file_get_filename         (GvaInputFile *input_file);

Returns the filename for `input_file`.

`input_file` : | a GvaInputFile
Returns : | filename for `input_file`

### gva_input_file_get_format ()

    const gchar *       gva_input_file_get_format           (GvaInputFile *input_file);

Returns a description of the INP header format. Possible formats are "INP simple format", "INP extended format", and "INP version x.y".

`input_file` : | a GvaInputFile
Returns : | description of the header format

### gva_input_file_get_game ()

    const gchar *       gva_input_file_get_game             (GvaInputFile *input_file);

Returns the corresponding ROM name for `input_file`.

`input_file` : | a GvaInputFile
Returns : | corresponding ROM name for `input_file`

### gva_input_file_get_origin ()

    const gchar *       gva_input_file_get_origin           (GvaInputFile *input_file);

Returns a description of the MAME program that recorded the INP file.

`input_file` : | a GvaInputFile
Returns : | description of the MAME program that recorded the INP file

### gva_input_file_get_timestamp ()

    time_t              gva_input_file_get_timestamp        (GvaInputFile *input_file);

Returns an approximation of when the game recording began.

`input_file` : | a GvaInputFile
Returns : | approximation of when the game recording began
