ATOMICOR(3G)                    [FIXME: manual]                   ATOMICOR(3G)

NAME
       atomicOr - perform an atomic logical OR operation to a variable

DECLARATION
       int atomicOr(inout int mem, int data);

       uint atomicOr(inout uint mem, uint data);

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

       data
           The data to be logically ORed with to mem.

DESCRIPTION
       atomicOr performs an atomic logical OR with data to the contents of mem
       and returns the original contents of mem from before the logical
       operation occurred. 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.
