VC++中ZeroMemory函数移植到linux要改成什么函数

void *memset( void *dest, int c, size_t count )

首地明帆址 设漏槐罩置返闹值 长度

头文件memory.h

用c++打开一个文件夹的方法如下：可以实现单选文件或者多选文件，代码如下：

需引入头文件#include "CommDlg.h"

[cpp] view plaincopy

TCHAR szBuffer[MAX_PATH] = {0}

OPENFILENAME ofn= {0}

ofn.lStructSize = sizeof(ofn)

ofn.hwndOwner = m_hWnd

ofn.lpstrFilter = _T("Exe文件(*.exe)\0*.exe\0所有文件(*.*)\0*.*\0")//要选择的文件后缀

ofn.lpstrInitialDir = _T("D:\\Program Files"誉租)//默认的文件路径

ofn.lpstrFile = szBuffer//存放文件的缓冲区

ofn.nMaxFile = sizeof(szBuffer)/sizeof(*szBuffer)

ofn.nFilterIndex = 0

ofn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST | OFN_EXPLORER //标志如果是多选要加上OFN_ALLOWMULTISELECT

BOOL bSel = GetOpenFileName(&ofn)

这样就可以打开选择文件对话瞎虚袭框了。可以选择需要的文件。szBuffer是存放的选择磨兄的文件路径。
