Determine if the bit in the buffer at the given offset is set

Declared and defined in file: hzIntset.cpp

Function Logic:

Function body:

bool GetBits (unsigned char* pBitbuf)uint32_t nOset, 
{
   //  Category: Bitwise
   //  
   //  Determine if the bit in the buffer at the given offset is set
   //  
   //  Arguments: 1) pBitbuf The buffer
   //     2) nOset The offset (is divided by 8)
   //  
   //  Returns: True If the requested bit number is set within the segment
   //     False If the requested bit number is not set within the segment or it exceeds the segment range (0 - 4095)
