Backend-Specific Operations

Backend-Specific Operations — Execute backend-specific operations

Synopsis

GnomeVFSResult      gnome_vfs_file_control              (GnomeVFSHandle *handle,
                                                         const char *operation,
                                                         gpointer operation_data);

Description

Advanced file operations allow you to execute backend-specific commands. Currently, none of the GnomeVFSModules shipped with GnomeVFS includes useful operations, but they allow sophisticated module-specific code that can not be added to GnomeVFS because it would break abstraction.

Details

gnome_vfs_file_control ()

GnomeVFSResult      gnome_vfs_file_control              (GnomeVFSHandle *handle,
                                                         const char *operation,
                                                         gpointer operation_data);

Execute a backend dependent operation specified by the string operation. This is typically used for specialized vfs backends that need additional operations that gnome-vfs doesn't have. Compare it to the unix call ioctl(). The format of operation_data depends on the operation. Operation that are backend specific are normally namespaced by their module name.

handle :

handle of the file to affect.

operation :

operation to execute.

operation_data :

data needed to execute the operation.

Returns :

an integer representing the success of the operation.
