DESCRIPTION Registers a new property with a property list class. The property will exist in all property list objects of that class after this routine is finished. The name of the property must not already exist. The default property value must be provided and all new property lists created with this property will have the property value set to the default provided. Any of the callback routines may be set to NULL if they are not needed. Zero-sized properties are allowed and do not store any data in the property list. These may be used as flags to indicate the presence or absence of a particular piece of information. The 'default' pointer for a zero-sized property may be set to NULL. The property 'create' & 'close' callbacks are called for zero-sized properties, but the 'set' and 'get' callbacks are never called. The 'create' callback is called when a new property list with this property is being created. H5P_prp_create_func_t is defined as: typedef herr_t (*H5P_prp_create_func_t)(hid_t prop_id, const char *name, size_t size, void *initial_value); where the parameters to the callback function are: hid_t prop_id; IN: The ID of the property list being created. const char *name; IN: The name of the property being modified. size_t size; IN: The size of the property value void *initial_value; IN/OUT: The initial value for the property being created. (The 'default' value passed to H5Pregister1) The 'create' routine may modify the value to be set and those changes will be stored as the initial value of the property. If the 'create' routine returns a negative value, the new property value is not copied into the property and the property list creation routine returns an error value. The 'set' callback is called before a new value is copied into the property. H5P_prp_set_func_t is defined as: typedef herr_t (*H5P_prp_set_func_t)(hid_t prop_id, const char *name, size_t size, void *value); where the parameters to the callback function are: hid_t prop_id; IN: The ID of the property list being modified. const char *name; IN: The name of the property being modified. size_t size; IN: The size of the property value void *new_value; IN/OUT: The value being set for the property. The 'set' routine may modify the value to be set and those changes will be stored as the value of the property. If the 'set' routine returns a negative value, the new property value is not copied into the property and the property list set routine returns an error value. The 'get' callback is called before a value is retrieved from the property. H5P_prp_get_func_t is defined as: typedef herr_t (*H5P_prp_get_func_t)(hid_t prop_id, const char *name, size_t size, void *value); where the parameters to the callback function are: hid_t prop_id; IN: The ID of the property list being queried. const char *name; IN: The name of the property being queried. size_t size; IN: The size of the property value void *value; IN/OUT: The value being retrieved for the property. The 'get' routine may modify the value to be retrieved and those changes will be returned to the calling function. If the 'get' routine returns a negative value, the property value is returned and the property list get routine returns an error value. The 'delete' callback is called when a property is deleted from a property list. H5P_prp_del_func_t is defined as: typedef herr_t (*H5P_prp_del_func_t)(hid_t prop_id, const char *name, size_t size, void *value); where the parameters to the callback function are: hid_t prop_id; IN: The ID of the property list the property is deleted from. const char *name; IN: The name of the property being deleted. size_t size; IN: The size of the property value void *value; IN/OUT: The value of the property being deleted. The 'delete' routine may modify the value passed in, but the value is not used by the library when the 'delete' routine returns. If the 'delete' routine returns a negative value, the property list deletion routine returns an error value but the property is still deleted. The 'copy' callback is called when a property list with this property is copied. H5P_prp_copy_func_t is defined as: typedef herr_t (*H5P_prp_copy_func_t)(const char *name, size_t size, void *value); where the parameters to the callback function are: const char *name; IN: The name of the property being copied. size_t size; IN: The size of the property value void *value; IN: The value of the property being copied. The 'copy' routine may modify the value to be copied and those changes will be stored as the value of the property. If the 'copy' routine returns a negative value, the new property value is not copied into the property and the property list copy routine returns an error value. The 'close' callback is called when a property list with this property is being destroyed. H5P_prp_close_func_t is defined as: typedef herr_t (*H5P_prp_close_func_t)(const char *name, size_t size, void *value); where the parameters to the callback function are: const char *name; IN: The name of the property being closed. size_t size; IN: The size of the property value void *value; IN: The value of the property being closed. The 'close' routine may modify the value passed in, but the value is not used by the library when the 'close' routine returns. If the 'close' routine returns a negative value, the property list close routine returns an error value but the property list is still closed. GLOBAL VARIABLES COMMENTS, BUGS, ASSUMPTIONS The 'set' callback function may be useful to range check the value being set for the property or may perform some tranformation/translation of the value set. The 'get' callback would then [probably] reverse the transformation, etc. A single 'get' or 'set' callback could handle multiple properties by performing different actions based on the property name or other properties in the property list. I would like to say "the property list is not closed" when a 'close' routine fails, but I don't think that's possible due to other properties in the list being successfully closed & removed from the property list. I suppose that it would be possible to just remove the properties which have successful 'close' callbacks, but I'm not happy with the ramifications of a mangled, un-closable property list hanging around...

DESCRIPTION Inserts a temporary property into a property list. The property will exist only in this property list object. The name of the property must not already exist. The value must be provided unless the property is zero- sized. Any of the callback routines may be set to NULL if they are not needed. Zero-sized properties are allowed and do not store any data in the property list. These may be used as flags to indicate the presence or absence of a particular piece of information. The 'value' pointer for a zero-sized property may be set to NULL. The property 'close' callback is called for zero-sized properties, but the 'set' and 'get' callbacks are never called. The 'set' callback is called before a new value is copied into the property.

The 'set' routine may modify the value to be set and those changes will be stored as the value of the property. If the 'set' routine returns a negative value, the new property value is not copied into the property and the property list set routine returns an error value.

The 'get' routine may modify the value to be retrieved and those changes will be returned to the calling function. If the 'get' routine returns a negative value, the property value is returned and the property list get routine returns an error value.

The 'copy' routine may modify the value to be copied and those changes will be stored as the value of the property. If the 'copy' routine returns a negative value, the new property value is not copied into the property and the property list copy routine returns an error value. The 'compare' callback is called when a property list with this property is compared to another property list. H5P_prp_compare_func_t is defined as: typedef int (*H5P_prp_compare_func_t)( void *value1, void *value2, size_t size); where the parameters to the callback function are: const void *value1; IN: The value of the first property being compared. const void *value2; IN: The value of the second property being compared. size_t size; IN: The size of the property value The 'compare' routine may not modify the values to be compared. The 'compare' routine should return a positive value if VALUE1 is greater than VALUE2, a negative value if VALUE2 is greater than VALUE1 and zero if VALUE1 and VALUE2 are equal. The 'close' callback is called when a property list with this property is being destroyed.

The 'get' callback would then [probably] reverse the transformation, etc. A single 'get' or 'set' callback could handle multiple properties by performing different actions based on the property name or other properties in the property list. There is no 'create' callback routine for temporary property list objects, the initial value is assumed to have any necessary setup already performed on it.
