question: gets the next n bits and increases input pointer . this is equivalent to peekbits followed by dropbits , except for correct error handling . concode_field_sep int bits_in_buffer concode_elem_sep int buffer concode_elem_sep int window_start concode_elem_sep byte[] window concode_elem_sep int window_end concode_field_sep int peekBits concode_elem_sep boolean needsInput concode_elem_sep int getAvailableBits concode_elem_sep void reset concode_elem_sep void dropBits concode_elem_sep int getAvailableBytes concode_elem_sep void skipToByteBoundary concode_elem_sep int copyBytes concode_elem_sep void setInput
target: int function ( int arg0 ) { int loc0 = peekBits ( arg0 ) ; if ( loc0 >= 0 ) dropBits ( arg0 ) ; return loc0 ; }
