Detailed Description

Inline x86 assembly functions imported from Linux kernel headers circa version 2.4.18-41mdk.

#define ix86_atomic_read ( v ) ((v)->counter)

ix86_atomic_read - read atomic variable : pointer of type ix86_atomic_int_t

Atomically reads the value of . Note that the guaranteed useful range of an ix86_atomic_int_t is only 24 bits.

Definition at line 35 of file atomic_ix86.h.

#define ix86_atomic_set	(	v,
		i		)	(((v)->counter) = (i))

ix86_atomic_set - set atomic variable : pointer of type ix86_atomic_int_t : required value

Atomically sets the value of to . Note that the guaranteed useful range of an ix86_atomic_int_t is only 24 bits.
