Description</h2></div></div></div><p>Constant Ids are Ids of strings that are often needed. They are defined to ease programming and reduce the number of pool_str2id calls. The constant Ids are part of the binary ABI of libsolv, a minor version update will only add new constants and not change existing Ids to maintain compatible. The on-disk solv format works does not use the fixed Ids, but instead references the strings, so solv files can still be read when the ABI is broken.</p></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="_special_strings"></a>3.
