Class context_error

boost::compute::context_error — A run-time OpenCL context error.

Synopsis

// In header: <boost/compute/exception/context_error.hpp>


class context_error : public exception {
public:
  // construct/copy/destruct
  context_error(const context *, const char *, const void *, size_t);
  ~context_error();

  // public member functions
  const context * get_context() const;
  const char * what() const;
};

Description

The context_error exception is thrown when the OpenCL context encounters an error condition. Boost.Compute is notified of these error conditions by registering an error handler when creating context objects (via the pfn_notify argument to the clCreateContext() function).

This exception is different than the opencl_error exception which is thrown as a result of error caused when calling a single OpenCL API function.
