Detailed Description

Implementation of Boolean arrays.

Function Documentation

and_barray()

barray * and_barray	(	barray *	a1,
		barray *	a2 )

Bitwise conjunction of two Boolean arrays of the same size.

Attention

If the arrays have distinct size, a NULL pointer is returned.

Returns

A new array containing the bitwise conjunction.

Parameters

a1	The first array of Booleans.
a2	The second array of Booleans.

and_barray_mod()

void and_barray_mod	(	barray *	a1,
		barray *	a2 )

Bitwise conjunction of two Boolean arrays of the same size. Modifies the first array.

Attention

If the arrays have distinct size, the first array is not modified.

Parameters

a1	The first array of Booleans.
a2	The second array of Booleans.

copy_barray()

barray * copy_barray

(

barray *

a

)

Copy of an array of Booleans.

Returns

The copy.

Parameters

a	The array of Booleans.

create_barray()

barray * create_barray

(

uint

size

)

Creation of an array of Booleans.

Remarks

All cells are initialized to the false value.

Returns

The array.

Parameters

size

The size

delete_barray()

void delete_barray

(

barray *

a

)

Release of an array of Booleans.

Parameters

a	The array of Booleans.

getsize_barray()

uint getsize_barray

(

barray *

a

)

Computation of the size of an array of Booleans.

Returns

The size of the array.

Parameters

a	The array of Booleans.

getval_barray()

bool getval_barray	(	barray *	a,
		uint	i )

Returns the value of a cell in an array of Booleans.

Returns

The Boolean value.

Parameters

a	The array of Booleans.
i	The cell.

or_barray()

barray * or_barray	(	barray *	a1,
		barray *	a2 )

Bitwise disjunction of two Boolean arrays of the same size.

Attention

If the arrays have distinct size, a NULL pointer is returned.

Returns

A new array containing the bitwise disjunction.

Parameters

a1	The first array of Booleans.
a2	The second array of Booleans.

or_barray_mod()

void or_barray_mod	(	barray *	a1,
		barray *	a2 )

Bitwise disjunction of two Boolean arrays of the same size. Modifies the first array.

Attention

If the arrays have distinct size, the first array is not modified.

Parameters

a1	The first array of Booleans.
a2	The second array of Booleans.

setfalse_barray()

void setfalse_barray	(	barray *	a,
		uint	i )

Sets a cell to false in an array of Booleans.

Parameters

a	The array of Booleans.
i	The cell.

settrue_barray()

void settrue_barray	(	barray *	a,
		uint	i )

Sets a cell to true in an array of Booleans.

Parameters

a	The array of Booleans.
i	The cell.
