| Name | Type | Description |
|---|---|---|
| hDoc | HIG_PDF_DOC | The document whose Info dictionary key is obtained. |
| szInfoKey | LPCSTR | The name of the Info dictionary key whose value is obtained. |
| szBuffer | LPSTR | Result buffer containing the value associated with infoKey. If buffer is NULL, the method will just return the number of bytes required. |
| nSize | LONG | The maximum number of bytes that can be written into buffer. |
| lpnBytes | LPLONG | If szBuffer is NULL, the number of bytes in the specified key's value. If szBuffer is not NULL, returns the number of bytes copied into buffer, excluding the terminating NULL. You must pass at least the length + 1 as the buffer size since the routine adds a '\0' terminator to the data, even though the data is not a C string (it can contain embedded '\0's). |

See Section 10.2.1 in the PDF Reference for information about Info dictionaries. All values in the Info dictionary should be strings; other data types such as numbers and Booleans should not be used as values in the Info dictionary.
Users may define their own Info dictionary entries. In this case, it is strongly recommended that the key have the developer's prefix assigned by the Adobe Solutions Network.
