Description:
HTML Wrap
classhdf-rm-section

Given a text description of a datatype, this function creates an HDF5 datatype and returns the datatype identifier. The text description of the datatype has to comply with the lang_type definition of HDF5 datatypes. Currently, only the DDL(H5LT_DDL) is supported. The complete DDL definition of HDF5 datatypes can be found in the last chapter of the HDF5 User’s Guide.

An example of DDL definition of enum type is shown as follows.

“H5T_ENUM { H5T_NATIVE_INT; 
            “Bob”        0;
            “Elena”      1;
            “Quincey”    2;      
            “Frank”      3;      }”
