Increment the context reference count.

cl_int clRetainContext ( cl_context context)



The context to retain.


clCreateContext and clCreateContextFromType perform an implicit retain. This is very helpful for 3rd party libraries, which typically get a context passed to them by the application. However, it is possible that the application may delete the context without informing the library. Allowing functions to attach to (i.e. retain) and release a context solves the problem of a context being used by a library no longer being valid.


Returns CL_SUCCESS if the function is executed successfully, or CL_INVALID_CONTEXT if context is not a valid OpenCL context.
