+/** This function returns an array with copies of all known bidirectional edges.
+ * The edges are copied to capture the mesh state at call time, since edges
+ * mutate frequently. The nodes pointed to within the meshlink_edge_t type
+ * are not copies; these are the same pointers that one would get from a call
+ * to meshlink_get_all_nodes().
+ *
+ * @param mesh A handle which represents an instance of MeshLink.
+ * @param edges A pointer to a previously allocated array of pointers to
+ * meshlink_edge_t, or NULL in which case MeshLink will
+ * allocate a new array. The application CANNOT supply an
+ * array it allocated itself with malloc, but CAN use
+ * the return value from the previous call to this function
+ * (which is the preferred way).
+ * The pointers in the array are valid until meshlink_close() is called.
+ * ATTENTION: The pointers and values should never be modified
+ * by the application!!!
+ * @param nmemb A pointer to a variable holding the number of nodes that
+ * are stored in the array. In case the @a nodes @a
+ * argument is not NULL, MeshLink might call realloc()
+ * on the array to change its size.
+ * The contents of this variable will be changed to reflect
+ * the new size of the array.
+ * @return A pointer to an array containing pointers to all known
+ * edges, or NULL in case of an error.
+ * If the @a edges @a argument was not NULL, then the
+ * retun value can be either the same value or a different
+ * value. If the new values is NULL, then the old array
+ * will have been freed by Meshlink.
+ * The caller must call free() on each element of this
+ * array (but not the contents of said elements),
+ * as well as the array itself when it is finished.
+ * ATTENTION: The pointers and values should never be modified
+ * by the application!!!
