in thread How perl debugger breakpoint works?
Every debugger needs to call ptrace
- For a start, ptrace is a linux api.
Do you think other operating systems don't have debuggers?
- Secondly, ptrace (or an equivalent) is only required if your are tracing at assembler level.
Perl's debugger operates at the perl opcode level, each of which may represent many hundreds or thousands of assembler instructions.
ptrace is not used by perl's debugger.
