And can anybody explain, why is it so ? (I mean checking for -1, and the switch(errno){}.) AFAIK, syscall returns us a number (on i386 it is in eax) and we can use it. Is errno a kernel thing, or GLIBC ? Haven't we a return code in eax, after int 0x80 ? (sorry, but I never worked on Linux on other architectures)
Best regards.
