modbus_set_indication_timeout - Man Page

void modbus_set_indication_timeout(modbus_t *ctx, uint32_t to_sec, uint32_t to_usec);

The modbus_set_indication_timeout() function shall set the timeout interval used by a server to wait for a request from a client.

The value of to_usec argument must be in the range 0 to 999999.

If both to_sec and to_usec are zero, this timeout will not be used at all. In this case, the server will wait forever.

The function shall return 0 if successful. Otherwise it shall return -1 and set errno.

EINVAL

The argument ctx is NULL or to_usec is larger than 1000000.
