概要
Win 32 应用程序编程接口 (API) 中的许多 C 运行时功能具有直接等效项。 这篇文章列出 C 运行时函数按类别与他们的 Win 32 命令对照表或单词"none"如果没有等效的存在。

注意： 后跟一个星号 (!) 的这些函数是 16-bit C 运行时仅的一部分。 是唯一 32 位 C 运行时函数中最后一节列出单独。 所有其他函数对这两个 C 运行时间都是一样的。

注意 1： 在 Win 32 API 中不存在的 _harderr 函数。 但是，大部分它们的功能，可通过结构化的异常处理。
NOTE 2: The time functions are based on that is not used in Win32 format。 there
are that are documented in Help file specific Win32 time functions。
注意 3： 本文档中列出的虚拟内存函数是特定于 MS-DOS 环境的被写入访问超出 640K 在 MS-DOS 中可用 RAM 的内存。 因为 Win 32 中不存在此限制，应该能使用标准的内存分配函数。
NOTE 4: While _pclose() and _popen() do not have
direct Win32 equivalents，can (with some work) simulate with following calls:
_popen CreatePipe
CreateProcess
_pclose WaitForSingleObject
CloseHandle
NOTE 5: GetFileInformationByHandle() is for _fstat() C
Run-time function Win32 equivalent. however，GetFileInformationByHandle() is not
supported by Win32s version 1.1。 is supported in Win32s 1.2。 GetFileSize()，GetFileAttributes()，GetFileTime()，and
GetFileTitle() are supported by Win32s 1.1 and 1.2。
