The null-terminated import symbol name immediately follows its associated Import Header. The following values are defined for the Name Type field in the Import Header, indicating how the name is to be used to generate the correct symbols representing the import:
| Constant | Value | Description |
| IMPORT_ORDINAL | 0 | The import is by ordinal. This indicates that the value in the Ordinal/Hint field of the Import Header is the import's ordinal. If this constant is not specified, then the Ordinal/Hint field should always be interpreted as the import's hint. |
| IMPORT_NAME | 1 | The import name is identical to the public symbol name. |
| IMPORT_NAME_NOPREFIX | 2 | The import name is the public symbol name, but skipping the leading ?, @, or optionally _. |
| IMPORT_NAME_UNDECORATE | 3 | The import name is the public symbol name, but skipping the leading ?, @, or optionally _, and truncating at the first @. |
