Recovering from a DllCall crash

[Tippex]

Is there any way to recover and carry on running an app after a DllCall becomes unresponsive?

The problem is that I need to run this dll  call and sometimes it will fail and never return  

(AutoIt3.exe ended.rc:-1073741819).

DllCall("msvcrt.dll", "int:cdecl", "memcmp", "ptr", $ptr1, "ptr", $ptr2, "int", $smallest)

The closest I can get to a solution is _OnAutoItErrorRegister

'?do=embed' frameborder='0' data-embedContent>>

but that seems to need my script to close and restart rather than just carrying on with the code after the DllCall

Make sure that all pointers are valid and the length does not exceed the allocated memory size.

DllCall("msvcrt.dll", "int:cdecl", "memcmp", "ptr", $ptr1, "ptr", $ptr2, "uint_ptr", $smallest)
