    66}}}
    7 This takes a result, reads its output file(s), parses them into a memory structure,
    8 and returns (via the 'data' argument) a pointer to this structure.

    119 * Zero on success,
    12  * ERR_OPENDIR if there was a transient error, e.g. the output file is on a network volume that is not available.
    13   The validator will try this result again later.
    14  * Any other return value indicates a permanent error.
    15   Example: an output file is missing, or has a syntax error.
    16   The result will be marked as invalid.

    30 You must link these functions with the files validator.cpp, validate_util.cpp, and validate_util2.cpp.

     33== Example ==
     34Here's an example in which the output file contains an integer and a double. Two results are considered equivalent if the integer is equal and the doubles differ by no more than 0.01.

     36This example uses [wiki:BackendUtilities utility functions] get_output_file_path() and try_fopen().
