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_buid_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, 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_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 –createlibrary 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 –createlibrary link option or program was created by clBuildProgram or an executable binary is loaded using clCreateProgramWithBinary.

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.
