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
