Meaning of the built in functions

[Ramin]

Hi, where can I get access to the definition and meaning and definition of the built in functions and headers of nrf51822? for instance what does this mean: uint8_t err_code = NRF_SUCCESS

@Ramin: Please give more information in your question. I don't know what you are asking about. The definition, and assignment of init value "uint8_t err_code = NRF_SUCCESS" is just to make sure err_code is created with value = 0 (NRF_SUCCESS) so that if it's not used then it will not cause any assertion.
