## Description

Applications can use the `gnome_vfs_get_file_info()` family of operations to retrieve file information, as this operation can be quite costly in terms of time (specilly when sniffing the MIME type) applications can specify which information need at any time, reducing the performance impact.

All of these operations use a GnomeVFSFileInfo data structure that holds the file information, there are several methods that can be used to manipulate this information. See GnomeVFSFileInfo for more information.

## Details

### gnome_vfs_get_file_info ()

    GnomeVFSResult      gnome_vfs_get_file_info             (const gchar *text_uri,
                                                             GnomeVFSFileInfo *info,
                                                             GnomeVFSFileInfoOptions options);

Retrieve information about `text_uri`. The information will be stored in `info`.

`text_uri` : | uri of the file for which information will be retrieved.
`info` : | pointer to a GnomeVFSFileInfo object that will hold the information for the file on return.
`options` : | options for retrieving file information.
Returns : | an integer representing the result of the operation.

### gnome_vfs_get_file_info_uri ()

    GnomeVFSResult      gnome_vfs_get_file_info_uri         (GnomeVFSURI *uri,
                                                             GnomeVFSFileInfo *info,
                                                             GnomeVFSFileInfoOptions options);

Retrieve information about `text_uri`. The information will be stored in `info`.

`uri` : | uri of the file for which information will be retrieved.
`info` : | pointer to a GnomeVFSFileInfo object that will hold the information for the file on return.
`options` : | options for retrieving file information.
Returns : | an integer representing the result of the operation.

### gnome_vfs_get_file_info_from_handle ()

    GnomeVFSResult      gnome_vfs_get_file_info_from_handle (GnomeVFSHandle *handle,
                                                             GnomeVFSFileInfo *info,
                                                             GnomeVFSFileInfoOptions options);

Retrieve information about an open file. The information will be stored in `info`.

`handle` : | handle of the file for which information must be retrieved.
`info` : | pointer to a GnomeVFSFileInfo object that will hold the information for the file on return.
`options` : | options for retrieving file information.
Returns : | an integer representing the result of the operation.

### gnome_vfs_set_file_info_uri ()

    GnomeVFSResult      gnome_vfs_set_file_info_uri         (GnomeVFSURI *uri,
                                                             GnomeVFSFileInfo *info,
                                                             GnomeVFSSetFileInfoMask mask);

Set file information for `uri`; only the information for which the corresponding bit in `mask` is set is actually modified.

### Note

`info`'s `valid_fields` is not required to contain the GnomeVFSFileInfoFields corresponding to the specified GnomeVFSSetFileInfoMask fields of `mask`. It is assumed that the `info` fields referenced by `mask` are valid.

`uri` : | a uri.
`info` : | information that must be set for the file.
`mask` : | bit mask representing which fields of `info` need to be set.
Returns : | an integer representing the result of the operation.

### gnome_vfs_set_file_info ()

    GnomeVFSResult      gnome_vfs_set_file_info             (const gchar *text_uri,
                                                             GnomeVFSFileInfo *info,
                                                             GnomeVFSSetFileInfoMask mask);

Set file information for `uri`; only the information for which the corresponding bit in `mask` is set is actually modified.

### Note

`info`'s `valid_fields` is not required to contain the GnomeVFSFileInfoFields corresponding to the specified GnomeVFSSetFileInfoMask fields of `mask`. It is assumed that the `info` fields referenced by `mask` are valid.

`text_uri` : | string representing the file location.
`info` : | information that must be set for the file.
`mask` : | bit mask representing which fields of `info` need to be set.
Returns : | an integer representing the result of the operation.
