Trigger a debugger breakpoint.
#define NS_BREAKPOINT | ( | ) | ns3::BreakpointFallback() |
Inserts a breakpoint instruction (or equivalent system call) into the code for selected machines.
When an NS_ASSERT cannot verify its condition, this macro is used. Falls back to calling ns3::BreakpointFallback() for architectures where breakpoint assembly instructions are not supported.

void ns3::BreakpointFallback | ( | ) |
fallback breakpoint function
This function is used by the NS_BREAKPOINT() macro as a fallback for when breakpoint assembly instructions are not available. It attempts to halt program execution either by a raising SIGTRAP, on unix systems, or by dereferencing a null pointer.
Normally you should not call this function directly.
we test here to allow a debugger to change the value of the variable 'a' to allow the debugger to avoid the subsequent segfault.
