| <p>@param handle The handle pointer from a successful call to |
| Persistence_open(). |
| @param key A string used as the key for the data to be put in the store. The |
| key is later used to retrieve data from the store with Persistence_get(). |
| @param bufcount The number of buffers to write to the persistence store. |
| @param buffers An array of pointers to the data buffers associated with |

| @param buflens An array of lengths of the data buffers. <i>buflen[n]</i> |
| gives the length of <i>buffer[n]</i>. |

| <h2>Search Tricks</h2> |
| |
| <p> |
| Prefix searches with a type followed by a colon (e.g. |
| <code>fn:</code>) to restrict the search to a given type. |
| </p> |
| |
| <p> |
| Accepted types are: <code>fn</code>, <code>mod</code>, |
| <code>struct</code>, <code>enum</code>, |
| <code>trait</code>, <code>type</code>, <code>macro</code>, |
| and <code>const</code>. |
| </p> |
| |
| <p> |
| Search functions by type signature (e.g. |
| <code>vec -> usize</code> or <code>* -> vec</code>) |
