Function Documentation

BIT_VECTOR ExpandBitVector	(	BIT_VECTOR	Vector,
		int	NewNumBits
	)

This routine uses realloc to increase the size of the specified bit vector.

Globals:

• none

Parameters

Vector	bit vector to be expanded
NewNumBits	new size of bit vector

Returns

New expanded bit vector.

void FreeBitVector

(

BIT_VECTOR

BitVector

)

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 nullptr, then the count is printed to stderr.

Globals:

• BitVectorCount count of number of bit vectors allocated

Parameters

BitVector

bit vector to be freed

                                         {
  if (BitVector) {
    Efree(BitVector);
  }
}                                /* FreeBitVector */

BIT_VECTOR NewBitVector

(

int

NumBits

)

Allocate and return a new bit vector large enough to hold the specified number of bits.

Globals:

• BitVectorCount number of bit vectors allocated

Parameters

NumBits

number of bits in new bit vector

Returns

New bit vector.
