clCreateProgramWithBinary - Creates a program object for a context, and loads the binary bits specified by binary into the program object.
cl_program clCreateProgramWithBinary(cl_context context, cl_uint num_devices, const cl_device_id *device_list, const size_t *lengths, const unsigned char **binaries, cl_int *binary_status, cl_int *errcode_ret);
The devices associated with the program object will be the list of devices specified by device_list. The list of devices specified by device_list must be devices associated with context.
The program binaries specified by binaries contain the bits that describe one of the following:
The program binary can consist of either or both of device-specific code and/or implementation-specific intermediate representation (IR) which will be converted to the device-specific code.
OpenCL allows applications to create a program object using the program source or binary and build appropriate program executables. This can be very useful as it allows applications to load program source and then compile and link to generate a program executable online on its first instance for appropriate OpenCL devices in the system. These executables can now be queried and cached by the application. Future instances of the application launching will no longer need to compile and link the program executables. The cached executables can be read and loaded by the application, which can help significantly reduce the application initialization time.
Returns a valid non-zero program object and errcode_ret is set to CL_SUCCESS if the program object is created successfully. Otherwise, it returns a NULL value with one of the following error values returned in errcode_ret:
clCreateProgramWithSource(3clc), clReleaseProgram(3clc), clRetainProgram(3clc), classDiagram(3clc)
