DEFAULT_DISPLAYCOUNT

#define DEFAULT_DISPLAYCOUNT   50

Definition at line 50 of file Dp.h.

DEFAULT_THRESHOLD

#define DEFAULT_THRESHOLD   1000

One millisecond.

Definition at line 49 of file Dp.h.

DP_DEBUG

#define DP_DEBUG   0

The value assigned to DP_DEBUG controls which debug output is generated. Set it to ZERO to disable.

PERF_INIT_CUM_DATA

#define PERF_INIT_CUM_DATA

(

t

)

{ 0ULL, PERF_MAXDUR, 0ULL, (t), 0U }

Initialize one PERF_CUM_DATA structure instance for token t.

This parameterized macro takes a single argument, t, which is expected to resolve to a pointer to an ASCII string literal. This parameter may take any one of the following forms:

• PERF_INIT_CUM_DATA("Token") A string literal
• PERF_INIT_CUM_DATA(pointer) A pointer – CHAR8 *pointer;
• PERF_INIT_CUM_DATA(array) Address of an array – CHAR8 array[N];

Definition at line 75 of file Dp.h.

PERF_MAXDUR

#define PERF_MAXDUR   0xFFFFFFFFFFFFFFFFULL

Definition at line 53 of file Dp.h.

WITHIN_LIMIT

#define WITHIN_LIMIT	(		C,
			L
	)		( ((L) == 0) || ((C) < (L)) )

Determine whether 0 <= C < L. If L == 0, return true regardless of C.
