以下是我的进展: let files = fs::read_dir(".").unwrap(); .filter_map(Result::ok)
.filter(|d| if let Some(e) = d.path().extension() { e == "txt" } else {false})
mmap手册页说明".. otherwise, it shall return a value of MAP_FAILED and set errno to indicate the error..."
我在/usr/src/linux/mm/mmap.c下查找了mmap的内核代码,但我找不到mmap返回MAP_FAILED的位置。
我需要并行处理条目列表并验证结果。有人能帮我在Scala上实现这一点吗?FileList = List { "/temp/File1", "/temp/File2","/temp/File3","/temp/File4"........}
Future { getRecCount(file) } // Need to create a List with all Futures现在我需要检查所有期货的结果,直到它完成
getRecCount -将计
