It works fine on my mac (10.5 on i386) but on the mac of one of my client, he have this error: Can't get 'kern.version' from sysctl: Bad file descriptor When I asked him to do a sysctl -A, I saw that kern.version is available: http://pastebin.com/f395945d What can be the problem? The code (c++) I used to get sysctl: string getsysctlstr(const string &name) { string value("Unknown"); size_t len; char *p; if(sysctlbyname(name.c_str(), NULL, &len, NULL, 0) == 0) { p = (char*)malloc(len); if(sysctlbyname(name.c_str(), p, &len, NULL, 0) == 0) { value = p; } else { nlwarning("SI: Can't get '%s' from sysctl: %s", name.c_str(), strerror (errno)); } free(p); } else { nlwarning("SI: Can't get '%s' from sysctl: %s", name.c_str(), strerror (errno)); } return value; } -- Vianney Lecroart http://www.mtp-target.org _______________________________________________ Do not post admin requests to the list.
