Optional extensions that implement atomic operations on 32bit signed and unsigned integers to locations in __local memory.
An application that wants to use this extension will need to include the #pragma
OPENCL EXTENSION cl_khr_local_int32_base_atomics : enable
directive in the OpenCL program source.
The atomic functions supported by the cl_khr_local_int32_base_atomics
extension are
described in the table below. All of the functions listed in the table are performed in one atomic transaction.
Function  Description 

int unsigned int 
Read the 32bit value (referred to as old )
stored at location pointed by p . Compute
(old + val ) and store result at location
pointed by p . The function returns old .

int unsigned int 
Read the 32bit value (referred to as old )
stored at location pointed by p . Compute
(old  val ) and store result at location
pointed by p . The function returns old .

int unsigned int 
Swaps the old value
stored at location p with new value given by
val ). Returns old value.

int unsigned int 
Read the 32bit value (referred to as old )
stored at location pointed by p . Compute
(old + 1) and store result at location
pointed by p . The function returns old .

int unsigned int 
Read the 32bit value (referred to as old )
stored at location pointed by p . Compute
(old  1) and store result at location
pointed by p . The function returns old .

int unsigned int 
Read the 32bit value (referred to as old )
stored at location pointed by p . Compute
(old == cmp ) ? val : old and store result at location pointed by p . The function returns old .
