# SocketTimeouts

Set timeouts for receiving and sending data for a socket system object.

```
bool  SocketTimeouts(
   int           socket,               // socket
   uint          timeout_send_ms,      // data sending timeout
   uint          timeout_receive_ms    // data obtaining timeout
   );

```

Parameters

socket

[in]  Socket handle returned by the [SocketCreate](/en/docs/network/socketcreate) function. When an incorrect handle is passed, the error 5270 (ERR_NETSOCKET_INVALIDHANDLE) is written to [_LastError](/en/docs/predefined/_lasterror).

timeout_send_ms

[in]  Data sending timeout in milliseconds.

timeout_receive_ms

[in]  Data obtaining timeout in milliseconds.

Return Value

Returns true if successful, otherwise false.

Note

Do not confuse system object timeouts with the ones set when reading data via [SocketRead](/en/docs/network/socketread). SocketTimeout sets timeouts once for a socket object in the operating system. These timeouts are to be applied to all functions for reading and sending data via this socket. In SocketRead, the timeout is set for a certain data reading operation.

The function can be called only from Expert Advisors and scripts, as they run in their own execution threads. If calling from an indicator, [GetLastError()](/en/docs/check/getlasterror) returns the error 4014 – "Function is not allowed for call".
