读取 ASCII 文件 TAB 替换为 NULL

发布于 2024-08-04 07:16:33 字数 547 浏览 5 评论 0原文

我在 Visual C++ 2008 中使用 CreateFileA 和 ReadFile 打开 ASCII 文本文件并将其读入内存。这工作正常（我可以查看内存中的内容），但有一个例外。由于某种原因，制表符 (0x09) 被更改为 NULL (0x00)。不用说，当我尝试解析文件时，这会造成严重破坏。有谁知道可能是什么原因造成的，或者我该如何解决它？

这就是我打开文件的方式：

hHandle = CreateFileA( pPath, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL );
GetFileSizeEx( hHandle, &tFileSize );
pBuf = (UINT8 *)malloc( tFileSize.LowPart );
ReadFile( hHandle, pBuf, tFileSize.LowPart, &dwBytesRead, NULL );

我的项目代码具有强大的错误处理功能，并且我没有收到任何错误。任何建议将不胜感激。

谢谢。

I'm using CreateFileA and ReadFile in Visual C++ 2008 to open and read an ASCII text file into memory. This works okay (I can view its contents in memory), but with one exception. For some reason the TAB characters (0x09) are being changed to NULLs (0x00). Needless to say, this is wreaking havoc when I try to parse the file. Does anybody know what might be causing this, or how I can fix it?

This is how I'm opening the file:

hHandle = CreateFileA( pPath, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL );
GetFileSizeEx( hHandle, &tFileSize );
pBuf = (UINT8 *)malloc( tFileSize.LowPart );
ReadFile( hHandle, pBuf, tFileSize.LowPart, &dwBytesRead, NULL );

My project code has robust error-handling, and I'm not getting any errors. Any suggestions would be appreciated.

Thanks.
