C++ (Cpp) fss_close Examples

Example #1

File: srv.c Project: themythfang/GridOS

static struct ko_section *map_file(struct ko_process *to, xstring name, page_prot_t prot, size_t __out *size)
{
	void *fp;
	size_t map_size;
	struct ko_section *map;

	//TODO: 此处应该使用to 的原始启动路径来做当前路径
	if (NULL == (fp = fss_open(kt_current()->current_dir, name)))
		goto err0;
	map_size = fss_get_size(fp);
	if (NULL == (map = create_file_map(to, fp, map_size, prot)))
		goto err1;
	if (size)
		*size = map_size;
	return map;
	
err1:
	fss_close(fp);
err0:
	return NULL;
}
