clRetainContext - Increment the context reference count.
cl_int clRetainContext(cl_context context);
clCreateContext(3clc) and clCreateContextFromType(3clc) 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. Otherwise, it returns one of the following values:
clCreateContext(3clc), clCreateContextFromType(3clc), clGetContextInfo(3clc), clReleaseContext(3clc), clGetContextInfo(3clc)
