Function Documentation
This routine uses realloc to increase the size of the specified bit vector.
Globals:
- Parameters:
-
Vector | bit vector to be expanded |
NewNumBits | new size of bit vector |
- Returns:
- New expanded bit vector.
- Note:
- Exceptions: none

This routine frees a bit vector. It also decrements the global counter that keeps track of the number of bit vectors allocated. If BitVector is NULL, then the count is printed to stderr.
Globals:
- BitVectorCount count of number of bit vectors allocated
- Parameters:
-
BitVector | bit vector to be freed |
- Note:
- Exceptions: none
