IsDebuggerPresent function (debugapi.h)
Determines whether the calling process is being debugged by a user-mode debugger.
BOOL IsDebuggerPresent();
If the current process is running in the context of a debugger, the return value is nonzero.
If the current process is not running in the context of a debugger, the return value is zero.
This function allows an application to determine whether or not it is being debugged, so that it can modify its behavior. For example, an application could provide additional information using the OutputDebugString function if it is being debugged.
To determine whether a remote process is being debugged, use the CheckRemoteDebuggerPresent function.
