When the programmer use 'open' function, the process is like below.
"open -> system call wrapper of open in Glibc -> syscall_open in kernel"
I found the wrapper of open, but there is no implementation like 'int $80'.
Code:
int
__open (file, oflag)
const char *file;
int oflag;
{
int mode;
if (file == NULL)
{
__set_errno (EINVAL);
return -1;
}
if (oflag & O_CREAT)
{
va_list arg;
va_start(arg, oflag);
mode = va_arg(arg, int);
va_end(arg);
}
__set_errno (ENOSYS);
return -1;
}
Please let me know where the wrapper of open is.
