So I suggest using : union indirect_params i = { .file_flags.flags = O_CLOEXEC, }; fd = syscall (__NR_indirect, &r, &i, sizeof (i)); Or better, you could avoid using 'union indirect_params' in user code, and only use the substructs for each function. /* define this in some include file of course */ struct file_flags { int flags; }; /* use it */ struct file_flags ff = { .flags = O_CLOEXEC}; fd = syscall (__NR_indirect, &r, &ff, sizeof(ff)); This to avoid to copy to kernel un-necessary data, and permitting futures changes. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
