Macro Definition Documentation

BARR_ARRAYSIZE

#define BARR_ARRAYSIZE

(

N

)

(((N) + BARR_ELBITS - 1) / BARR_ELBITS)

MACRO to compute the minimum number of elements that a buffer of BARR_ELTYPEs must have in order to store N bits.

Parameters

N	the number of bits to store.

Definition at line 60 of file packer.cpp.

BARR_BITNUM

#define BARR_BITNUM

(

N

)

((N) % BARR_ELBITS)

MACRO to compute the position where is stored the bit N, within its corresponding element of a buffer of BARR_ELTYPEs .

Parameters

N	indication of the bit.

Definition at line 74 of file packer.cpp.

BARR_CLEAR

#define BARR_CLEAR	(		barr,
			N
	)

Value:

    (((BARR_ELTYPE *) (barr))[BARR_ELNUM(N)] &= \
            ~((BARR_ELTYPE) 1 << BARR_BITNUM(N)))

MACRO to set to 0 the bit N of a buffer of BARR_ELTYPEs.

Parameters

barr	pointer to the buffer
N	indication of the bit.

Definition at line 90 of file packer.cpp.

BARR_ELBITS

#define BARR_ELBITS   (CHAR_BIT * sizeof(BARR_ELTYPE))

The size, in bits, of a BARR_ELTYPE (unsigned char).

Used for code portability.

Definition at line 53 of file packer.cpp.

BARR_ELNUM

#define BARR_ELNUM

(

N

)

((N) / BARR_ELBITS)

MACRO to compute the number of the element of a buffer of BARR_ELTYPEs where is stored the bit N.

Parameters

N	indication of the bit.

Definition at line 67 of file packer.cpp.

BARR_SET

#define BARR_SET	(		barr,
			N
	)

Value:

    (((BARR_ELTYPE *) (barr))[BARR_ELNUM(N)] |= (BARR_ELTYPE) 1 \
                    << BARR_BITNUM(N))

MACRO to set to 1 the bit N of a buffer of BARR_ELTYPEs.

Parameters

barr	pointer to the buffer
N	indication of the bit.

Definition at line 81 of file packer.cpp.

BARR_TEST

#define BARR_TEST	(		barr,
			N
	)

Value:

    (((BARR_ELTYPE *) (barr))[BARR_ELNUM(N)] & \
            ((BARR_ELTYPE) 1 << BARR_BITNUM(N)))

MACRO to test if the bit N of a buffer of BARR_ELTYPEs is set to 1.

Parameters

barr	pointer to the buffer
N	indication of the bit.

Definition at line 99 of file packer.cpp.

DEFAULT_DUMMY_CONTENT_LENGTH

#define DEFAULT_DUMMY_CONTENT_LENGTH   256
