-/**
- * @file chregistry.c
- * @brief Threads registry code.
- *
- * @addtogroup registry
- * @details Threads Registry related APIs and services.
- *
- * <h2>Operation mode</h2>
- * The Threads Registry is a double linked list that holds all the
- * active threads in the system.<br>
- * Operations defined for the registry:
- * - <b>First</b>, returns the first, in creation order, active thread
- * in the system.
- * - <b>Next</b>, returns the next, in creation order, active thread
- * in the system.
- * .
- * The registry is meant to be mainly a debug feature, for example,
- * using the registry a debugger can enumerate the active threads
- * in any given moment or the shell can print the active threads
- * and their state.<br>
- * Another possible use is for centralized threads memory management,
- * terminating threads can pulse an event source and an event handler
- * can perform a scansion of the registry in order to recover the
- * memory.
- * @pre In order to use the threads registry the @p CH_USE_REGISTRY option
- * must be enabled in @p chconf.h.
