    SubjectOT: why no file copy() libc/syscall ??
    it may be orribly RTFM... but writing a simple framework I realized 
    there is no libc/POSIX/whoknows
    copy(const char* dest_file_name, const char* src_file_name)

    What is the technical reason???

    I understand that there may be little space for kernel side
    optimizations in this area but anyway I'm surprised I have to write

    < the bits to clone the metadata of src_file_name on opening
    dest_file_name >
    const int BUFSIZE = 1<<12;
    char buffer[BUFSIZE];
    int nrb;
    while((nrb = read(infd, buffer, BUFSIZE) != -1) {
    ret = write(outfd, buffer, nrb);
    if(ret != nrb) {...}

    instead of something similar to:
