## Functions

### ogmrip_fs_unref ()

    void
    ogmrip_fs_unref (gchar *filename,
                     gboolean do_unlink);

If `do_unlink` is `TRUE`, recursively removes `filename` then frees the memory pointed to by `filename` .

#### Parameters

filename | A path to a filename |
do_unlink | `TRUE` to also remove the file |

### ogmrip_fs_get_tmp_dir ()

    const gchar *
    ogmrip_fs_get_tmp_dir (void);

Returns OGMRip's temporary directory.

#### Returns

The temporaty directory

### ogmrip_fs_set_tmp_dir ()

    void
    ogmrip_fs_set_tmp_dir (const gchar *dir);

Sets OGMRip's temporary directory. If `dir` is NULL, OGMRip's temporary directory will be the system's temporary directory.

#### Parameters

dir | The new temporary directory |

### ogmrip_fs_mkdir ()

    gboolean
    ogmrip_fs_mkdir (const gchar *path,
                     mode_t mode,
                     GError **error);

Create the all the directories in `path` , if they do not already exist.

#### Parameters

path | A path of directories |
mode | The file mode |
error | A location to return an error of type G_FILE_ERROR |

#### Returns

`TRUE` on success, `FALSE` if an error was set

### ogmrip_fs_rmdir ()

    gboolean
    ogmrip_fs_rmdir (const gchar *path,
                     gboolean recursive,
                     GError **error);

If `recusive` is `FALSE`, removes the directory of `path` if it is empty. If `recusive` is `TRUE`, also removes its content recursively.

#### Parameters

path | A path to a directory |
recursive | `TRUE` to remove the directory and its content recursively |
error | A location to return an error of type G_FILE_ERROR |

#### Returns

`TRUE` on success, `FALSE` if an error was set

### ogmrip_fs_mktemp ()

    gchar *
    ogmrip_fs_mktemp (const gchar *tmpl,
                      GError **error);

Creates a file in OGMRip's temporary directory (as returned by `ogmrip_fs_get_tmp_dir()`).

#### Parameters

tmpl | Template for file name, as in `g_mkstemp()`, basename only |
error | A location to return an error of type G_FILE_ERROR |

#### Returns

The actual name used, or NULL

    ogmrip_fs_mkftemp (const gchar *tmpl,
                       GError **error);

Creates a fifo in OGMRip's temporary directory (as returned by `ogmrip_fs_get_tmp_dir()`).

#### Parameters

tmpl | Template for fifo name, basename only |
error | A location to return an error of type G_FILE_ERROR |

#### Returns

The actual name used, or NULL

### ogmrip_fs_mkdtemp ()

    gchar *
    ogmrip_fs_mkdtemp (const gchar *tmpl,
                       GError **error);

Creates a directory in OGMRip's temporary directory (as returned by `ogmrip_fs_get_tmp_dir()`).

#### Parameters

tmpl | Template for directory name, basename only |
error | A location to return an error of type G_FILE_ERROR |

#### Returns

The actual name used, or NULL

### ogmrip_fs_lntemp ()

    gchar *
    ogmrip_fs_lntemp (const gchar *oldpath,
                      const gchar *newtmpl,
                      gboolean symln,
                      GError **error);

Creates a link in OGMRip's temporary directory (as * returned by `ogmrip_fs_get_tmp_dir()`) to æn existing file.

#### Parameters

oldpath | A path to an existing file |
newtmpl | Template for link name, basename only |
symln | `TRUE` to create a symbolic link |
error | A location to return an error of type G_FILE_ERROR |

#### Returns

### ogmrip_fs_open_tmp ()

    gint
    ogmrip_fs_open_tmp (const gchar *tmpl,
                        gchar **name_used,
