Microsoft Specific

Causes a breakpoint in your code, where the user will be prompted to run the debugger.

void __debugbreak();  

__debugbreakx86, ARM, x64<intrin.h>

The __debugbreak compiler intrinsic, similar to DebugBreak, is a portable Win32 way to cause a breakpoint.

System_CAPS_ICON_note.jpg Note

When compiling with /clr, a function containing __debugbreak will be compiled to MSIL. asm int 3 causes a function to be compiled to native. For more information, see __asm.

For example:

main() {  

is similar to:

main() {  
   __asm {  
      int 3  

on an x86 computer.

This routine is only available as an intrinsic.
