AnchorName	description

Description:

HTML Wrap

class	hdf-rm-section

H5T_GET_MEMBER_VALUE returns the value of the enumeration datatype member memb_no.

The member value is returned in a user-supplied buffer pointed to by value. Values returned in value will be of the enumerated type’s base type, that is, the datatype used by H5T_ENUM_CREATE when the enumerated type was created.

The value buffer must be at least large enough to hold a value of that base type. If the size is unknown, you can determine it with H5T_GET_SIZE, H5Tget_size(dtype_id), where dtype_id is set to the base type.
