and
struct CyU3PI2cPreamble_t {
uint8_t buffer[8];
uint8_t length;
uint16_t ctrlMask;
};
how to use the buffer? how to use length? how to use ctrlMask?

Please look at cyu3i2c.h in C:\Cypress\FX3 SDK\firmware\u3p_firmware\inc, you should be able to find the necessary details through the comments in the file.
