本文實(shí)例講述了C++進(jìn)程間共享數(shù)據(jù)的實(shí)現(xiàn)方法，分享給大家供大家參考。具體實(shí)現(xiàn)方法如下：
int main(int argc, char *argv[])
{
//RecursiveDelete("C://20_128//");
//SelfRun("runModel");
//進(jìn)程間內(nèi)存共享
LPCTSTR lpName= "hello";
LPCTSTR lpContent = "123456";
HANDLE hMap = ::OpenFileMapping(FILE_MAP_ALL_ACCESS, FALSE, lpName);
if (NULL == hMap) //打開失敗
{
//創(chuàng)建
hMap = ::CreateFileMapping(INVALID_HANDLE_VALUE, NULL, PAGE_EXECUTE_READWRITE, 0, strlen(lpContent), lpName);
if (hMap == NULL)
{
return -1;
}
//寫入
LPVOID lpBase = ::MapViewOfFile(hMap, FILE_MAP_ALL_ACCESS, 0, 0, 0);
strcpy((char*)lpBase, lpContent);
printf("write %s/n", lpContent);
}
else
{
//打開成功就只讀取
LPVOID lpBase = ::MapViewOfFile(hMap, FILE_MAP_ALL_ACCESS, 0, 0, 0);
if (lpBase == NULL)
{
return -1;
}
printf("read %s/n",(char*)lpBase);
}
getchar();
return 0;
}
希望本文所述對大家的C++程序設(shè)計有所幫助。
