     75 ** Description      This function is called by NFA to read in data from the
     76 **                  previously opened file.
     77 **
     78 ** Parameters       p_buf   - buffer to read the data into.
     79 **                  nbytes  - number of bytes to read into the buffer.
     80 **
     81 ** Returns          void

     83 **                  Note: Upon completion of the request, nfa_nv_ci_read () is
