C Specification

To release a context, call the function:

cl_int clReleaseContext(
    cl_context context);

Parameters

  • context specifies the OpenCL context to release.

Description

clReleaseContext decrements the context reference count. After the reference count becomes zero and all the objects attached to context (such as memory objects, command-queues) are released, the context is deleted. Using this function to release a reference that was not obtained by creating the object or by calling clRetainContext causes undefined behavior.

clReleaseContext returns CL_​SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors:

  • CL_​INVALID_​CONTEXT if context is not a valid OpenCL context.

  • CL_​OUT_​OF_​RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device.

  • CL_​OUT_​OF_​HOST_​MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.
