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.
