atomicXor - perform an atomic logical exclusive OR operation to a variable

Declaration

intatomicXor(inoutintmem,intdata);uintatomicXor(inoutuintmem,uintdata);

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.

Name

Parameters

mem
           The variable to use as the target of the operation.

       data
           The data to be logically exclusive ORed with to mem.
