/*******************************************************************************
**
** Function         nfc_hal_nv_co_read
**
** Description      This function is called by NFA to read in data from the
**                  previously opened file.
**
** Parameters       p_buf   - buffer to read the data into.
**                  nbytes  - number of bytes to read into the buffer.
**
** Returns          void
**
**                  Note: Upon completion of the request, nfa_nv_ci_read () is
**                        called with the buffer of data, along with the number
**                        of bytes read into the buffer, and a status.  The
**                        call-in function should only be called when ALL requested
**                        bytes have been read, the end of file has been detected,
**                        or an error has occurred.

**
** Description      This function is called by io to send file data to the

**
** Parameters       p_buf   - buffer to read the data from.
**                  nbytes  - number of bytes to write out to the file.
**
** Returns          void
**
**                  Note: Upon completion of the request, nfa_nv_ci_write () is
**                        called with the file descriptor and the status.  The
