函數內有Return一個值回去,但在宣告函數時卻沒有說要傳值回去???

邏輯上的錯誤,改一下吧!

unsigned char MasterWrute (insigned char val)

小弟在使用PICDEM做I2C傳送的時候...發生了一點小問題...
但是我實在不知道該怎麼解決...請各位大大昇出援手吧@@

PICDEM為主控端..要傳送DATA給SLAVE..
我是使用C18...

可是當我使用 MasterWrite(); 的動作的時候跑出

Error [1203] too few arguments in function call

的錯誤...以下是我的function

I2C_RESULT MasterWrite(unsigned char val)
{
IdleI2C(); // ensure module is idle

if ( WriteI2C( val ) ) // data byte for EEPROM
return I2C_BUS_COLLISION; // set error for write collision


IdleI2C();
if ( !SSPCON2_ACKSTAT )
return I2C_SUCCESS;
return I2C_NAK;
}

希望各位大大能只點一下
感激不盡
