Macro Definition Documentation

◆ _AC

#define _AC	(	num,
		suf
	)	__tok(num, suf)

Create an integer usable in both C and Assembly, even when suf is needed.

Definition at line 16 of file numbers.h.

◆ KB

#define KB ( num ) (_AC(num, ULL) << 10)

Express num in Kilobytes.

Definition at line 23 of file numbers.h.

◆ MB

#define MB ( num ) (_AC(num, ULL) << 20)

Express num in Megabytes.

Definition at line 26 of file numbers.h.

◆ GB

#define GB ( num ) (_AC(num, ULL) << 30)

Express num in Gigabytes.

Definition at line 29 of file numbers.h.

◆ TB

#define TB ( num ) (_AC(num, ULL) << 40)

Express num in Terabytes.

Definition at line 32 of file numbers.h.

◆ IS_ALIGNED

#define IS_ALIGNED	(	val,
		align
	)	(((val) & ((align) - 1)) == 0)

Return a boolean indicating whether val is aligned on align.

align is required to be exact power of two.

Definition at line 38 of file numbers.h.

◆ MASK_EXTR

#define MASK_EXTR	(	v,
		m
	)	(((v) & (m)) / ((m) & -(m)))

Definition at line 40 of file numbers.h.

◆ MASK_INSR

#define MASK_INSR	(	v,
		m
	)	(((v) * ((m) & -(m))) & (m))

Definition at line 41 of file numbers.h.

◆ _p

#define _p ( v ) ((void*)(unsigned long)(v))

Express an abitrary integer v as void *.

Definition at line 48 of file numbers.h.

◆ _u

#define _u ( v ) ((unsigned long)(v))

Express an arbitrary value v as unsigned long.

Definition at line 53 of file numbers.h.
