Posting a solution if anyone else gets perplexed like me ...
Basically, you have to start writing to I2C with the address of slave SHIFTED 1 bit to the left (last bit 0 for writes, or 1 for reads) so the above code would be something like:
//writing part
char Data={"\0x90\0x01\x11\x22"};
Start(context);
Write (Context,Data,4); //equals ioctl and i2c_smbus_write_word_data above
Stop(context);
//reading part
Start(Context);
Data[1]=\0x00; // ADS1015_REG_POINTER_CONVERT=0x00
Write (Context,Data,2); //set the register for read
Stop(context);
Start(Context);
Data[0]=\0x91;
Write (Context,Data,1); //State you want to read from address 0x48 (0x48<<1)|1
Read (Context,2); //read the word (2 bytes) of data
Stop(Context);
