<p>APR_OS_START_USERERR are reserved for applications that use APR that layer their own error codes along with APR's. Note that the error immediately following this one is set ten times farther away than usual, so that users of apr have a lot of room in which to declare custom error codes.</p>
<p>In general applications should try and create unique error codes. To try and assist in finding suitable ranges of numbers to use, the following ranges are known to be used by the listed applications. If your application defines error codes please advise the range of numbers it uses to <a href="#" onclick="location.href='mai'+'lto:'+'dev'+'@a'+'pr.'+'ap'+'ach'+'e.'+'org'; return false;">dev@a<span style="display: none;">.nosp@m.</span>pr.a<span style="display: none;">.nosp@m.</span>pache<span style="display: none;">.nosp@m.</span>.org</a> for inclusion in this list.</p>
