Function Documentation

ObitIOHistoryFITS* newObitIOHistoryFITS (  gchar *  name, ObitInfoList *  info, ObitErr *  err )

Public: Constructor. Initializes class if needed on first call. Parameters: name  Name [optional] for object info  InfoList defining file err  ObitErr for reporting errors. Returns: the new object.

void ObitIOHistoryFITSClassInit (  void   )

Public: Class initializer.

void ObitIOHistoryFITSClear (  gpointer  inn  )

Private: Deallocate members. Does (recursive) deallocation of parent class members. Parameters: inn  Pointer to the object to deallocate.

ObitIOCode ObitIOHistoryFITSClose (  ObitIOHistoryFITS *  in, ObitErr *  err )

Public: Close. Parameters: in  Pointer to object to be closed. err  ObitErr for reporting errors. Returns: error code, OBIT_IO_OK=> OK

ObitIOHistoryFITS* ObitIOHistoryFITSCopy (  ObitIOHistoryFITS *  in, ObitIOHistoryFITS *  out, ObitErr *  err )

Public: Copy constructor. The result will have pointers to the more complex members. Parent class members are included but any derived class info is ignored. Parameters: in  The object to copy out  An existing object pointer for output or NULL if none exists. err  Obit error stack object. Returns: pointer to the new object.

ObitIOCode ObitIOHistoryFITSFlush (  ObitIOHistoryFITS *  in, ObitErr *  err )

Public: Flush. Parameters: in  Pointer to object to be accessed. err  ObitErr for reporting errors. Returns: return code, OBIT_IO_OK=> OK

gboolean ObitIOHistoryFITSSame (  ObitIO *  in, ObitInfoList *  in1, ObitInfoList *  in2, ObitErr *  err )

Public: Are underlying structures the same. This test is done using values entered into the ObitInfoList in case the object has not yet been opened. Parameters: in  ObitIO for test in1  ObitInfoList for first object to be tested in2  ObitInfoList for second object to be tested err  ObitErr for reporting errors. Returns: TRUE if to objects have the same underlying structures else FALSE
