用法和参数可以参照上面的ReadFile的说明。 在使用这个函数的时候,它打开的文件的句柄一定要有写的权限。 如果用和上面的示例那个调用函数一样的参数来调用WriteFile函数的话,是把数据添加到文件的末尾处。 GetFileSize 函数原型 DWORD WINAPI GetFileSize( HANDLE hFile, LPDWORD lpFileSizeHigh ); 参数. hFile:文件 Using the WIN32 API Functions CreateFile, ReadFile, WriteFile, SetFilePointer from C# What if for some reason you need to use the WIN32 API to read and write files? I know FileStream can do a lot of what the WIN32 API can do, but this is a "what if".... a hypothetical situation, ok! (don't think for one second I did this because I thought I couldn't seek to a spot in a file and write some DWORD nRead; ReadFile(hout, buff2, 40, &nRead, NULL); Also, rename hin and hout. share | improve this answer | follow | answered Oct 24 '10 at 22:25.

This is about the code. // Your code: // System Programming.cpp : Defines the entry point for the console The ReadFile function may fail with ERROR_NOT_ENOUGH_QUOTA, which means the calling process's buffer could not be page-locked. For additional information, see SetProcessWorkingSetSize . If part of a file is locked by another process and the read operation overlaps the locked portion, this function fails. ReadFile() is not a substitute for fscanf(). Since the file doesn't appear to contain anything that's suitable for human eyes, most definitely not a string, the only proper way to display something recognizable is by showing the hex representation of the bytes. Use printf() with the %x format specifier in a loop.
