+nghttp2_session_get_effective_recv_data_length
+==============================================
+
+Synopsis
+--------
+
+*#include <nghttp2/nghttp2.h>*
+
+.. function:: int32_t nghttp2_session_get_effective_recv_data_length(nghttp2_session *session)
+
+    
+    Returns the number of DATA payload in bytes received without
+    WINDOW_UPDATE transmission for a connection.  The local (receive)
+    window size can be adjusted by `nghttp2_submit_window_update()`.
+    This function takes into account that and returns effective data
+    length.  In particular, if the local window size is reduced by
+    submitting negative window_size_increment with
+    `nghttp2_submit_window_update()`, this function returns the number
+    of bytes less than actually received.
+    
+    This function returns -1 if it fails.
