GetBitOffset()
GetBitOffset()
Return value
integer
Comments
Returns the current bit offset that is used in NextNBits or PeekNBits .
Example
raw = 'FOFO';# 1111000011110000 binary
result1 = GetNBits ( raw, 2, 4 );
result2 = PeekNBits(5);
result3 = NextNBits(2);
Trace ( "Offset = ", GetBitOffset() );
The example generates this Trace output:
Offset = D
PeekNBits()
PeekNBits(<bit_count integer>)
Return value
integer, list or raw.
Comments
Reads bit_count bits from the data source. The difference between
PeekNBits and NextNBits is that PeekNBits does not advance the global
bit offset. PeekNBits can be used to make decisions about how to parse the next
fields without affecting subsequent calls to NextNBits . If PeekNBits is called
without a prior call to GetNBits , the result is undefined. Note that bits are indexed
starting at bit 0.
Example
raw = 'FOFO';# 1111000011110000 binary
result1 = GetNBits ( raw, 2, 4 );
result2 = PeekNBits(5);
