typedef struct _MyData {
int val1;
int val2;
} MYDATA, *PMYDATA;
DWORD WINAPI ThreadRun1(LPVOID lpParam)
{
while(1)
{
printf("a\n");
Sleep(1000);
}
return 1L;
}
DWORD WINAPI ThreadRun2( LPVOID lpParam)
{
while(1)
{
printf("b\n");
Sleep(1000);
}
return 1L;
}
void main(void)
{
PMYDATA pData;
pData = (PMYDATA)HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY,sizeof(MYDATA));
CreateThread(NULL,0,ThreadRun1,NULL,0,NULL);
CreateThread(NULL,0,ThreadRun2,pData,0,NULL);
while(1);
