Function Documentation

void oro_atomic_add	(	oro_atomic_t *	a,
		int	n
	)

Add n to a

void ORO_ATOMIC_CLEANUP

(

oro_atomic_t *

a

)

Cleans up all resources allocated durint the setup of atomic structure a.

void oro_atomic_dec

(

oro_atomic_t *

a

)

Decrement a atomically

int oro_atomic_dec_and_test

(

oro_atomic_t *

a

)

Decrement a atomically and test for zero.

void oro_atomic_inc

(

oro_atomic_t *

a

)

Increment a atomically

int oro_atomic_inc_and_test

(

oro_atomic_t *

a

)

Increment a atomically and test for zero.

int oro_atomic_read

(

oro_atomic_t *

a

)

Returns the current counter value of the atomic structure a.

void oro_atomic_set	(	oro_atomic_t *	a,
		int	n
	)

Sets the current counter value of the atomic structure a to n.

void ORO_ATOMIC_SETUP	(	oro_atomic_t *	a,
		int	n
	)

Initializes the uninitialized atomic structure a with a counter value of 'n'.

void oro_atomic_sub	(	int	n,
		oro_atomic_t *	a,
		int	n
	)

Substract n from a

int oro_atomic_sub_and_test	(	oro_atomic_t *	a,
		int	n
	)

Substract n from a and test for zero

int oro_cmpxchg	(	void volatile *	ptr,
		unsigned long	o,
		unsigned long	n
	)

Compare o with *ptr and swap with n if equal. Note: you need to implement this function for different sizes of pointers and payloads. You will probably need to implement this function as a macro to resolve this in a way compatible with C.
