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

__debugbreak |
x86, x64, ARM, ARM64 | <intrin.h> |
The __debugbreak compiler intrinsic, similar to DebugBreak, is a portable Win32 way to cause a breakpoint.
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() {
__debugbreak();
}is similar to:
main() {
__asm {
int 3
}
}on an x86 computer.
On ARM64, the __debugbreak intrinsic is compiled into the instruction brk #0xF000.
This routine is only available as an intrinsic.
