Macro Definition Documentation

H5_SIZEOF_HID_T

#define H5_SIZEOF_HID_T   H5_SIZEOF_INT64_T

The size of identifiers

H5I_INVALID_HID

#define H5I_INVALID_HID   (-1)

An invalid object ID. This is also negative for error return.

Typedef Documentation

H5I_free_t

typedef herr_t(* H5I_free_t) (void *)

A function for freeing objects. This function will be called with an object ID type number and a pointer to the object. The function should free the object and return non-negative to indicate that the object can be removed from the ID type. If the function returns negative (failure) then the object will remain in the ID type.

H5I_iterate_func_t

typedef herr_t(* H5I_iterate_func_t) (hid_t id, void *udata)

[H5I_search_func_t_snip]

The type of H5Iiterate() callback functions [H5I_iterate_func_t_snip]

H5I_search_func_t

typedef int(* H5I_search_func_t) (void *obj, hid_t id, void *key)

[H5I_search_func_t_snip]

The type of a function to compare objects & keys

hid_t

typedef int64_t hid_t

Type of atoms to return to users
