Description
The atomic_init function non-atomically initializes the atomic object
pointed to by obj to the value value.
// Requires OpenCL C 3.0 or newer.
void atomic_init(volatile __global A *obj, C value)
void atomic_init(volatile __local A *obj, C value)
// Requires OpenCL C 2.0, or OpenCL C 3.0 or newer and the
// __opencl_c_generic_address_space feature.
void atomic_init(volatile A *obj, C value)Examples:
local atomic_int guide;
if (get_local_id(0) == 0)
atomic_init(&guide, 42);
work_group_barrier(CLK_LOCAL_MEM_FENCE);
The function variant that uses the generic address space, i.e. no
explicit address space is listed, requires support for OpenCL
C 2.0, or OpenCL C 3.0 or newer and the __opencl_c_
feature.
