sleep()与_sleep()的疑问？

[liuying1982000]

请教各位大哥，我用vc新建了一个基于对话框的工程，在有的文件里sleep()能通过，有的文件里_sleep()才能通过，请告诉我这是怎么回事？为什么要这样,我该怎么区分？

Sleep
This function suspends the execution of the current thread for a specified interval.

void Sleep(
DWORD dwMilliseconds);

Parameters

dwMilliseconds

Specifies the time, in milliseconds, for which to suspend execution. A value of zero causes the thread to relinquish the remainder of its time slice to any other thread of equal priority that is ready to run. If there are no other threads of equal priority ready to run, the function returns immediately, and the thread continues execution. A value of INFINITE causes an infinite delay


_Sleep

This command tells the system to sleep the specified amount of time.

void _Sleep( long msSleep )
Parameters

msSleep
Specifies the time to sleep in milliseconds.
