Context (const vector< Device > &devices, const cl_context_properties *properties=nullptr, void(CL_CALLBACK *notifyFptr)(const char *, const void *, size_type, void *)=nullptr, void *data=nullptr, cl_int *err=nullptr) | |
Constructs a context including a list of specified devices. | |
Context (const Device &device, const cl_context_properties *properties=nullptr, void(CL_CALLBACK *notifyFptr)(const char *, const void *, size_type, void *)=nullptr, void *data=nullptr, cl_int *err=nullptr) | |

Constructor from cl_context - takes ownership.
This effectively transfers ownership of a refcount on the cl_context into the new Context object.

Wraps clGetSupportedImageFormats().

Assignment operator from cl_context - takes ownership.
This effectively transfers ownership of a refcount on the rhs and calls clReleaseContext() on the value previously held by this instance.
Definition at line 3498 of file opencl.hpp.
Modify the default context to be used by subsequent operations. Will only set the default if no default was previously created.
Definition at line 3475 of file opencl.hpp.

inline |
Registers a destructor callback function with a context.
Wraps clSetContextDestructorCallback().
Each call to this function registers the specified callback function on a destructor callback stack associated with context. The registered callback functions are called in the reverse order in which they were registered. If a context callback function was specified when context was created, it will not be called after any context destructor callback is called.
