Typedef Documentation

  typedef enum CUfileOpError CUfileOpError

cufileop status enum.

Note:
    This file contains all the CUfileOpError error codes from GPUDirect Storage supported APIs

    on success the error code is set to CU_FILE_SUCCESS.

    The error code can be inspected using IS_CUFILE_ERR and CUFILE_ERRSTR.

    The error code if set to CU_FILE_CUDA_DRIVER_ERROR, then cuda error can be inspected using IS_CUDA_ERR and CU_FILE_CUDA_ERR.

    Data path errors are captured via standard error codes
