NAME

       mongoc_gridfs_find_one_with_opts - mongoc_gridfs_find_one_with_opts()

SYNOPSIS

          mongoc_gridfs_file_t *
          mongoc_gridfs_find_one_with_opts (mongoc_gridfs_t *gridfs,
                                            const bson_t *filter,
                                            const bson_t *opts,
                                            bson_error_t *error)
             BSON_GNUC_WARN_UNUSED_RESULT;

PARAMETERS

       • gridfs: A mongoc_gridfs_t.

       • filter: A bson_t containing the query to execute.

       • opts: A bson_t query options, including sort order and which fields to return. Can be NULL.

       • error: An optional location for a bson_error_t or NULL.

DESCRIPTION

       Find  the  first  GridFS file matching filter. If there is an error, NULL is returned and error is filled
       out; if there is no error but no matching file is found, NULL is returned and the error code  and  domain
       are 0.

       See mongoc_collection_find_with_opts for a description of the filter and opts parameters.

       This  function is considered a retryable read operation.  Upon a transient error (a network error, errors
       due to replica set failover, etc.) the operation is safely retried once.  If retryreads is false  in  the
       URI (see mongoc_uri_t) the retry behavior does not apply.

ERRORS

       Errors are propagated via the error parameter.

RETURNS

       Returns  a  newly  allocated  mongoc_gridfs_file_t  if  successful. You must free the resulting file with
       mongoc_gridfs_file_destroy() when no longer in use.
