+== NAME
+
+nng_http_handler_get_data - set extra data for HTTP handler
+
+== SYNOPSIS
+
+[source, c]
+-----------
+#include <nng/nng.h>
+
+void *nng_http_handler_get_data(nng_http_handler *handler, void *data,
+    void (*dtor)(void *));
+-----------
+
+== DESCRIPTION
+
+The `nng_http_handler_set_data()` function is used to set an additional
+_data_ for the _handler_.  The stored _data_ can be retrieved later
+in the handler function using
+<<nng_http_handler_get_data#,nng_http_handler_get_data(3)>>.
+
+Additionally, when the handler is deallocated, if _dtor_ is not `NULL`,
+then it will be called with _data_ as its argument.  The intended use of
+this function is deallocate any resources associated with _data_.
+
+== RETURN VALUES
+
+This function returns 0 on success, and non-zero otherwise.
+
+== ERRORS
+
+`NNG_ENOMEM`:: Insufficient free memory to perform the operation.
+`NNG_ENOTSUP`:: No support for HTTP in the library.
