Essentially the same code as %example_open()% function we saw earlier. php_stream *example_opener(php_stream_wrapper *wrapper, char *filename, char *mode, int options, char **opened_path, php_stream_context *context STREAMS_DC TSRMLS_DC) { php_stream *stream; struct my_stream_data *data; filename += sizeof("example://") - 1; data = emalloc(sizeof(struct my_stream_data)); data->filedes = open(filename, O_RDWR); stream = php_stream_alloc(&my_ops, data, NULL, mode); if (opened_path) { *opened_path = estrdup(filename); } return stream; }
