    SubjectRe: Intercepting system calls

    Hello Gaurav,

    Gaurav Saxena:

    For kernel space, CONFIG_KPROBES may help you.
    See Documentation/kprobes.txt in detail.

    For user space, $LD_PRELOAD may help you.
    You will need to develop your shared object library which contains
    your_unlink() and replaces the original unlink().
    See manual page.
