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


void __debugbreak();  


Intrinsic Architecture Header
__debugbreak x86, ARM, x64 <intrin.h>


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


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.
