1.30.4                                            Jun 08, 2025                         MONGOC_GRIDFS_FIND_ONE(3)

       This function shall execute a query on the underlying gridfs  implementation.  The  first  file  matching
       query  will  be  returned. 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.

       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 are propagated via the error parameter.

       • gridfs: A mongoc_gridfs_t.

       • query: A bson_t.

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

       A newly allocated mongoc_gridfs_file_t or NULL if no file could be found. You  must  free  the  resulting
       file with mongoc_gridfs_file_destroy() if non-NULL.
