SPI EEPROM & GPS logging

i have got exact same chip eeprom stated on website tutorial spieeprom. got hardware interfacing , work using code provided.

http://www.arduino.cc/en/tutorial/spieeprom

now appreciate understand how store "long int" number instead of "char" shown in code. website seems can write 128 bytes @ time , since in example used char (which 1 byte) spi transfered in following code:

for (int i=0;i<128;i++)
 {
   spi_transfer(buffer); //write data byte
 }

how change long int (which 4 bytes, 32 bits). how addressing affected?

ps: want store "latitude, longitude" comes out of tinygps library functions.

any sample code or nudge in right direction explain eeprom addressing , storage appreciated.

thanks

have peek @ how it's done here:
