Mode in which files are opened. If GNOME_VFS_OPEN_RANDOM is not used, the file will be have to be accessed sequentially.
GnomeVFSResult gnome_vfs_create (GnomeVFSHandle **handle, const gchar *text_uri, GnomeVFSOpenMode open_mode, gboolean exclusive, guint perm);
Create uri
according to mode open_mode
. On return, handle
will then
contain a pointer to a handle for the open file.
handle : |
A pointer to a pointer to a GnomeVFSHandle object |
text_uri : |
String representing the URI to create |
open_mode : |
mode to leave the file opened in after creation (or GNOME_VFS_OPEN_MODE_NONE
to leave the file closed after creation)
|
exclusive : |
Whether the file should be created in "exclusive" mode: i.e. if this flag is nonzero, operation will fail if a file with the same name already exists. |
perm : |
Bitmap representing the permissions for the newly created file (Unix style). |
Returns : | An integer representing the result of the operation |
GnomeVFSResult gnome_vfs_create_uri (GnomeVFSHandle **handle, GnomeVFSURI *uri, GnomeVFSOpenMode open_mode, gboolean exclusive, guint perm);
Create uri
according to mode open_mode
. On return, handle
will then
contain a pointer to a handle for the open file.
handle : |
A pointer to a pointer to a GnomeVFSHandle object |
uri : |
URI for the file to create |
open_mode : |
Open mode |
exclusive : |
Whether the file should be created in "exclusive" mode: i.e. if this flag is nonzero, operation will fail if a file with the same name already exists. |
perm : |
Bitmap representing the permissions for the newly created file (Unix style). |
Returns : | An integer representing the result of the operation |
GnomeVFSResult gnome_vfs_open (GnomeVFSHandle **handle, const gchar *text_uri, GnomeVFSOpenMode open_mode);
Open text_uri
according to mode open_mode
. On return, handle
will then
contain a pointer to a handle for the open file.
handle : |
A pointer to a pointer to a GnomeVFSHandle object |
text_uri : |
String representing the URI to open |
open_mode : |
Open mode |
Returns : | An integer representing the result of the operation |
GnomeVFSResult gnome_vfs_open_uri (GnomeVFSHandle **handle, GnomeVFSURI *uri, GnomeVFSOpenMode open_mode);
Open uri
according to mode open_mode
. On return, handle
will then
contain a pointer to a handle for the open file.
handle : |
A pointer to a pointer to a GnomeVFSHandle object |
uri : |
URI to open |
open_mode : |
Open mode |
Returns : | An integer representing the result of the operation |
GnomeVFSResult gnome_vfs_close (GnomeVFSHandle *handle);
Close file associated with handle
.
handle : |
A pointer to a GnomeVFSHandle object |
Returns : | An integer representing the result of the operation. |
GnomeVFSResult gnome_vfs_unlink (const gchar *text_uri);
Unlink text_uri
(i.e. delete the file).
text_uri : |
URI of the file to be unlinked |
Returns : | An integer representing the result of the operation |
GnomeVFSResult gnome_vfs_unlink_from_uri (GnomeVFSURI *uri);
Unlink uri
(i.e. delete the file).
uri : |
URI of the file to be unlinked |
Returns : | An integer representing the result of the operation |
GnomeVFSResult gnome_vfs_move_uri (GnomeVFSURI *old_uri, GnomeVFSURI *new_uri, gboolean force_replace);
Move a file from URI old_uri
to new_uri
. This will only work if old_uri
and new_uri
are on the same file system. Otherwise, it is necessary
to use the more general %gnome_vfs_xfer_uri()
function.
old_uri : |
Source URI |
new_uri : |
Destination URI |
force_replace : |
If TRUE , move target to new_uri even if there
is already a file at new_uri . If there is a file, it will be discarded.
|
Returns : | An integer representing the result of the operation. |
GnomeVFSResult gnome_vfs_move (const gchar *old_text_uri, const gchar *new_text_uri, gboolean force_replace);
Move a file from URI old_text_uri
to new_text_uri
. This will only work
if old_text_uri
and new_text_uri
are on the same file system. Otherwise,
it is necessary to use the more general %gnome_vfs_xfer_uri()
function.
old_text_uri : |
Source URI |
new_text_uri : |
Destination URI |
force_replace : |
if TRUE , perform the operation even if it unlinks an existing
file at new_text_uri
|
Returns : | An integer representing the result of the operation. |
GnomeVFSResult gnome_vfs_check_same_fs_uris (GnomeVFSURI *source_uri, GnomeVFSURI *target_uri, gboolean *same_fs_return);
Check if source_uri
and target_uri
are on the same file system.
source_uri : |
A URI |
target_uri : |
Another URI |
same_fs_return : |
Pointer to a boolean variable which will be set to TRUE
if source_uri and target_uri are on the same file system on return.
|
Returns : | An integer representing the result of the operation. |
GnomeVFSResult gnome_vfs_check_same_fs (const gchar *source, const gchar *target, gboolean *same_fs_return);
Return TRUE
if source
and target
are on the same file system.
source : |
A URI |
target : |
Another URI |
same_fs_return : |
Pointer to a boolean variable which will be set to TRUE
|
Returns : | An integer representing the result of the operation. |
gboolean gnome_vfs_uri_exists (GnomeVFSURI *uri);
Check if the URI points to an existing entity.
uri : |
A URI |
Returns : | TRUE if URI exists. |
GnomeVFSResult gnome_vfs_create_symbolic_link (GnomeVFSURI *uri, const gchar *target_reference);
Creates a symbolic link, or eventually, a URI link (as necessary)
at uri
pointing to target_reference
