Function Documentation

void midgard_blob_destroy (  MidgardBlob *  self  )

Destroy Midgard Blob instance. Parameters: self,MidgardBlob  self instance. Destroy Midgard Blob instance and all data associated with this instance. Any file handler assigned to destroyed instance will be freed as well. It's enough to call g_object_unref to destroy Midgard Blob. This method is hidden internally in MidgardObjectClass finalize method and it's added for readability.

GType midgard_blob_get_type (  void   )

Returns Midgard Blob Gtype value. Registers this type unless already registered. Definition at line 126 of file midgard_blob.c.

MidgardBlob midgard_blob_new (  MidgardConection *  mgd, MidgardObject *  attachment )

Instatiate new Midgard Blob. Parameters: mgd,MidgardConection  pointer attachment,MidgardObject  of MIDGARD_TYPE_ATTACHMENT type. Returns: MidgardBlob, newly instatiated MidgardBlob object. Instatiate new Midgard Blob object for the given midgard_attachment object. This is almost the same constructor as g_object_new, but unlike that one, midgard_object_new requires Midgard Connection handler's pointer. Initializes new Midgard Blob object and its internal data in currently used MidgardConnection context.

GIOChannel midgard_blob_read (  MidgardBlob *  self  )

Returns GIOChannel pointer for the given midgard_blob. Parameters: self,Midgard  Blob self instance Returns: GIOChannel which holds filename's content, NULL if there is no filename associated with midgard_attachment for the given Midgard Blob instance. Returned pointer is owned by midgard-core and should not be freed. Definition at line 46 of file midgard_blob.c. References MGD_ERR_USER_DATA, and midgard_set_error(). Here is the call graph for this function:

GIOChannel midgard_blob_write (  MidgardBlob *  self, const gchar *  content )

Returns GIOChannel pointer for written blob file. Parameters: self,MidgardBlob  self instance. content,content  which should be written to file. Returns: GIOChannel pointer if content has been successfully written to file. Otherwise returns NULL.
