clGetProgramBuildInfo

Returns build information for each device in the program object.

`cl_int clGetProgramBuildInfo (`	cl_program `program`,
	cl_device_id `device`,
	cl_program_build_info `param_name`,
	size_t `param_value_size`,
	void `*param_value`,
	size_t `*param_value_size_ret)`

Parameters

program

Specifies the program object being queried.

device

Specifies the device for which build information is being queried. device must be a valid device associated with program.

param_name

Specifies the information to query. The list of supported param_name types and the information returned in param_value by clGetProgramBuildInfo is described in the table below.

cl_program_build_info	Return Type and Info. returned in `param_value`
`CL_PROGRAM_BUILD_STATUS`	Return type: cl_build_status Returns the build, compile or link status, whichever was performed last on `program` for `device`. This can be one of the following: `CL_BUILD_NONE`. The build status returned if no clBuildProgram, clCompileProgram or clLinkProgram has been performed on the specified program object for `device`. `CL_BUILD_ERROR`. The build status returned if clBuildProgram, clCompileProgram or clLinkProgram whichever was performed last on the specified program object for `device` generated an error. `CL_BUILD_SUCCESS`. The build status returned if clBuildProgram, clCompileProgram or clLinkProgram whichever was performed last on the specified program object for `device` was successful. `CL_BUILD_IN_PROGRESS`. The build status returned if clBuildProgram, clCompileProgram or clLinkProgram whichever was performed last on the specified program object for `device` has not finished.
`CL_PROGRAM_BUILD_OPTIONS`	Return type: char[] Return the build, compile or link options specified by the `options` argument in clBuildProgram, clCompileProgram or clLinkProgram, whichever was performed last on `program` for `device`. If build status of `program` for `device` is `CL_BUILD_NONE`, an empty string is returned.
`CL_PROGRAM_BUILD_LOG`	Return type: char[] Return the build, compile or link log for clBuildProgram or clCompileProgram whichever was performed last on `program` for `device`. If build status of `program` for `device` is `CL_BUILD_NONE`, an empty string is returned.
`CL_PROGRAM_BINARY_TYPE`	Return type: cl_program_binary_type Return the program binary type for `device`. This can be one of the following values: `CL_PROGRAM_BINARY_TYPE_NONE`. There is no binary associated with `device`. `CL_PROGRAM_BINARY_TYPE_COMPILED_OBJECT`. A compiled binary is associated with `device`. This is the case if `program` was created using clCreateProgramWithSource and compiled using clCompileProgram or a compiled binary is loaded using clCreateProgramWithBinary. `CL_PROGRAM_BINARY_TYPE_LIBRARY`. A library binary is associated with `device`. This is the case if `program` was created by clLinkProgram which is called with the `–create-library` link option or if a library binary is loaded using clCreateProgramWithBinary. `CL_PROGRAM_BINARY_TYPE_EXECUTABLE`. An executable binary is associated with `device`. This is the case if `program` was created by clLinkProgram without the `–create-library` link option or program was created by clBuildProgram or an executable binary is loaded using clCreateProgramWithBinary. `CL_PROGRAM_BINARY_TYPE_INTERMEDIATE`. An intermediate (non-source) representation for the program is loaded as a binary. The program must be further processed with clCompileProgram or clBuildProgram. If processed with clCompileProgram, the result will be a binary of type `CL_PROGRAM_BINARY_TYPE_COMPILED_OBJECT` or `CL_PROGRAM_BINARY_TYPE_LIBRARY`. If processed with clBuildProgram, the result will be a binary of type `CL_PROGRAM_BINARY_TYPE_EXECUTABLE`.
`CL_PROGRAM_BUILD_GLOBAL_- VARIABLE_TOTAL_SIZE`	Return type: size_t The total amount of storage, in bytes, used by program variables in the global address space.

param_value

A pointer to memory where the appropriate result being queried is returned. If param_value is NULL, it is ignored.

param_value_size

Specifies the size in bytes of memory pointed to by param_value. This size must be ≥ size of return type as described in the table above.

param_value_size_ret

Returns the actual size in bytes of data copied to param_value. If param_value_size_ret is NULL, it is ignored.

Notes

A program binary (compiled binary, library binary or executable binary) built for a parent device can be used by all its sub-devices. If a program binary has not been built for a sub-device, the program binary associated with the parent device will be used.

A program binary for a device specified with clCreateProgramWithBinary or queried using clGetProgramInfo can be used as the binary for the associated root device, and all sub-devices created from the root-level device or sub-devices thereof.

Errors

Returns CL_SUCCESS if the function is executed successfully. Otherwise it returns the following:

Returns CL_INVALID_DEVICE if device is not in the list of devices associated with program.
Returns CL_INVALID_VALUE if param_name is not valid, or if size in bytes specified by param_value_size is < size of return type as described in the table above and param_value is not NULL.
Returns CL_INVALID_PROGRAM if program is a not a valid program object.
CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device.
CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.
