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 status of program for a specific device as given by device. This can be one of the following:

CL_BUILD_NONE. The build status returned if no build has been performed on the specified program object for device.

CL_BUILD_ERROR. The build status returned if the last call to clBuildProgram on the specified program object for device generated an error.

CL_BUILD_SUCCESS. The build status retrned if the last call to clBuildProgram on the specified program object for device was successful.

CL_BUILD_IN_PROGRESS. The build status returned if the last call to clBuildProgram on the specified program object for device has not finished.

CL_PROGRAM_BUILD_OPTIONS Return type: char[]

Return the build options specified by the options argument in clBuildProgram 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 log when clBuildProgram was called for device. If build status of program for device is CL_BUILD_NONE, an empty string is returned.

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 greater than or equal to the 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.

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 less than size of return type and param_value is not NULL.
  • Returns CL_INVALID_PROGRAM if program is a not a valid program object.
