３２ビットＣ言語の標準関数
_beginthread CreateThread
_cwait WaitForSingleObject GetExitCodeProcess
_endthread ExitThread
_findclose FindClose
_findfirst FindFirstFile
_findnext FindNextFile
_futime SetFileTime
_get_osfhandle ---
_open_osfhandle ---
_pclose See Note 4
_pipe CreatePipe
_popen See Note 4
Note 1: _harderr関数はＷｉｎ３２には存在しない。しかし、構造化例外処理で多くを解決できる。Note 2: 時間と日付に使われるデータ表現はＷｉｎ３２では使用しない。独自の構造体で処理する。
Note 3: The virtual memory functions listed in this document are specific to the MS-DOS environment and were written to access memory beyond the 640K of RAM available in MS-DOS. Because this limitation does not exist in Win32, the standard memory allocation functions should be used.
Note 4: While _pclose() and _popen() do not have direct Win32 equivalents,you can (with some work) simulate them with the following calls:
_popen CreatePipe
CreateProcess
_pclose WaitForSingleObject
CloseHandle
Note 5: GetFileInformationByHandle() is the Win32 equivalent for the
_fstat() C Run-time function. However, GetFileInformationByHandle() is not supported by Win32s version 1.1. It is supported in Win32s 1.2.
GetFileSize(), GetFileAttributes(), GetFileTime(), and GetFileTitle() are supported by Win32s 1.1 and 1.2.
