RETURN VALUE ------------ The function shall return 0 if successful. Otherwise it shall return -1 and set errno. EXAMPLE ------- [source,c] ------------------- uint32_t old_response_to_sec; uint32_t old_response_to_usec; /* Save original timeout */ modbus_get_response_timeout(ctx, &old_response_to_sec, &old_response_to_usec); /* Define a new and too short timeout! */ modbus_set_response_timeout(ctx, 0, 0); ------------------- SEE ALSO -------- linkmb:modbus_set_response_timeout[3] linkmb:modbus_get_byte_timeout[3] linkmb:modbus_set_byte_timeout[3] AUTHORS ------- The libmodbus documentation was written by Stéphane Raimbault
