The path and filename of the executable (and any sources) on the host, and a device.
[3] it detects problems in a program while letting it run and allows users to examine different registers.
This article describes the calling conventions used when programming x86 architecture microprocessors Calling conventions describe the interface of called code The order in which atomic (scalar) parameters, or individual parts of a complex parameter, are allocated how parameters are passed (pushed on the stack, placed in registers, or a mix of both) which registers the called function must. Call stack in computer science, a call stack is a stack data structure that stores information about the active subroutines and inline blocks of a computer program
A stack buffer overflow can be caused deliberately as part of an attack known as stack smashing If the affected program is running with special privileges, or accepts data from untrusted network hosts (e.g A webserver) then the bug is a potential security vulnerability. Ptrace is used by debuggers (such as gdb and dbx), by tracing tools like strace and ltrace, and by code coverage tools
Ptrace is also used by specialized programs to patch running programs, to avoid unfixed bugs or to overcome security features
