+### Description
+
+The function `httplib_printf()` can be used to send formatted strings over a connection. The functionality is comparable to the `printf()` family of functions in the standard C library. The function returns **0** when the connection has been closed, **-1** if an error occurred and otherwise the number of bytes written over the connection. Except for the formatting part, the `httplib_printf()` function is identical to the function [`httplib_write()`](httplib_write.md).
