Win Error Code 5 的含义 在Windows操作系统中,错误代码5(ERROR_ACCESS_DENIED)通常表示访问被拒绝。这通常意味着当前用户没有足够的权限来执行请求的操作。 可能导致WriteFile函数失败的原因 文件权限不足:尝试写入的文件可能受到权限保护,当前用户没有足够的权限进行写操作。 文件正在被其他程序使用:如果文件已被其他...
ERROR_BROKEN_PIPE 如果应用程序使用WriteFile函数写入管道时管道缓冲区已满,则写入操作可能不会立即完成。 当读取操作(使用ReadFile函数)使更多的系统缓冲区空间可用于管道时,写入操作将完成。 写入到缓冲区空间不足的非阻塞字节模式管道句柄时,WriteFile返回具有 *lpNumberOfBytesWrittennNumberOfBytesToWrite的 trueTRUE...
you also don't abort the execution of the WriteFile if CreateFile fails, so that could fail and then carry on. If it was security problems it wouldn't be returning ERROR_INCORRECT_FUNCTION but instead ERROR_ACCESS_DENIED.

This is only debug code at the moment.I know for certain that CreateFile does not fail and that WriteFile does fail - I have breakpoints on both calls. If any one of these fail, i manually terminate the application.I'm not getting an ERROR_INCORRECT_FUNCTION, more an ERROR_INVALID_...

I'm not getting an ERROR_INCORRECT_FUNCTION, more an ERROR_INVALID_FUNCTION which I presume means that one of the arguments has invalid data. Thursday, April 15, 2010 10:03 AM Updated code with error checking... 复制 int _tmain(int argc, _TCHAR* argv[]) { DWORD dwError; HDEVINFO ...
