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 `mg_printf()` function is identical to the function [`mg_write()`](mg_write.md). + +### See Also + +* [`mg_websocket_client_write();`](mg_websocket_client_write.md) +* [`mg_websocket_write();`](mg_websocket_write.md) +* [`mg_write();`](mg_write.md) |
