Detailed Description

template<class T, class B, bool A = false>
class PutBlock< T, B, A >

Access a block of memory.

Template Parameters
Tclass or type
Benumeration indicating endianess
Aflag indicating alignment

PutBlock() provides alternate write access to a block of memory. The enumeration B is BigEndian or LittleEndian. The flag A indicates if the memory block is aligned for class or type T. Repeatedly applying operator() results in advancing in the block of memory.

An example of writing two word32 values from a block of memory is shown below. After the code executes, the byte buffer will be {0,1,2,3,4,5,6,7}.

   word32 w1=0x03020100, w2=0x07060504;
   byte buffer[8];
   PutBlock<word32, LittleEndian> block(NULL, buffer);
   block(w1)(w2);
