edma_transfer definition question

I have a problem at using the "edma_transfer" function. In the example of edma_transfer, the edma_transfer.h has declared "triggerDmaUartTx(uint8_t channel, uint8_t * buff, uint32_t size); and triggerDmaUartRx(uint8_t channel, uint8_t * buff);" However, I don't see the specific definition, and it don't work without the specific definition. So, I am asking the original code for those two functions if any one can help. Thanks.
