NAME
atomicXor - perform an atomic logical exclusive OR operation to a variable
DECLARATION
int atomicXor(inout int mem, int data);
uint atomicXor(inout uint mem, uint data);
PARAMETERS
mem
The variable to use as the target of the operation.
data
The data to be logically exclusive ORed with to mem.
DESCRIPTION
atomicXor performs an atomic logical exclusive OR with data to the contents of mem and returns the
original contents of mem from before the logical operation occured. The contents of the memory being
updated by the atomic operation are guaranteed not to be modified by any other assignment or atomic
memory function in any shader invocation between the time the original value is read and the time the new
value is written.
Atomic memory functions are supported only for a limited set of variables. A shader will fail to compile
if the value passed to the mem argument of an atomic memory function does not correspond to a buffer or
shared variable. It is acceptable to pass an element of an array or a single component of a vector to the
mem argument of an atomic memory function, as long as the underlying array or vector is a buffer or
shared variable.
