Errors
Returns CL_SUCCESS returns a valid non-zero OpenCL buffer object and errcode_ret is set to CL_SUCCESS if
the buffer object is created successfully. Otherwise, it returns a NULL value with one of the following
error values returned in errcode_ret:
• CL_INVALID_CONTEXT if context is not a valid context.
• CL_INVALID_VALUE if values specified in flags are not valid.
• CL_INVALID_D3D11_RESOURCE_KHR if resource is not a Direct3D 11 buffer resource, if resource was
created with the D3D11_USAGE flag D3D11_USAGE_IMMUTABLE, if a cl_mem from resource has already been
created using clCreateFromD3D11BufferKHR, or if context was not created against the same Direct3D 11
device from which resource was created.
• CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL
implementation on the host.

Parameters
context
A valid OpenCL context created from a Direct3D 11 device.
flags
A bit-field that is used to specify usage information. May be CL_MEM_READ_ONLY, CL_MEM_WRITE_ONLY, or
CL_MEM_READ_WRITE. (See the table for clCreateBuffer(3clc) for more information.)
resource
A pointer to the Direct3D 11 buffer to share.
errcode_ret
An appropriate error code. If errcode_ret is NULL, no error code is returned.
