data : 

gnome_vfs_process_init ()

gboolean    gnome_vfs_process_init          (void);

Returns : 

gnome_vfs_process_new ()

GnomeVFSProcess* gnome_vfs_process_new      (const gchar *file_name,
                                             const gchar *const      argv[],
                                             GnomeVFSProcessOptions options,
                                             GnomeVFSProcessInitFunc init_func,
                                             gpointer init_data,
                                             GnomeVFSProcessCallback callback,
                                             gpointer callback_data);

Launch a new process. init_func is called immediately after calling fork(), and before closing the file descriptors and executing the program in the new process.

file_name : Name of the executable.
argv : NULL-terminated parameter list.
options : 
init_func : Function to be called before launching the process.
init_data : Value to pass to init_func.
callback : Function to invoke when the process die.
callback_data : Data to pass to callback when the process dies.
Returns : An opaque structure describing the launched process.

gnome_vfs_process_free ()

void        gnome_vfs_process_free          (GnomeVFSProcess *process);

Free process. This will not kill the process, but will prevent the associated callbacks to be called.

process : An existing process.
