<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<p>Allocate or free resources. </p>
<p>Allocation can fail only on out of memory. In such case they return NULL and leave the state as before call. Mainly function names are in the form tds_alloc_XX or tds_free_XXX. tds_alloc_XXX functions allocate structures and return pointer to allocated data while tds_free_XXX take structure pointers and free them. Some functions require additional parameters to initialize structure correctly. The main exception are structures that use reference counting. These structures have tds_alloc_XXX functions but instead of tds_free_XXX use tds_release_XXX. </p>
