From 591d270f4cb78aa28bf4425bd40ffa64369adf01 Mon Sep 17 00:00:00 2001 From: sobomax Date: Fri, 11 Oct 2002 11:43:09 +0000 Subject: - Add support for IPC_64 extensions into shmctl(2), semctl(2) and msgctl(2); - add wrappers for mmap2(2) and ftruncate64(2) system calls; - don't spam console with printf's when VFAT_READDIR_BOTH ioctl(2) is invoked; - add support for SOUND_MIXER_READ_STEREODEVS ioctl(2); - make msgctl(IPC_STAT) and IPC_SET actually working by converting from BSD msqid_ds to Linux and vice versa; - properly return EINVAL if semget(2) is called with nsems being negative.
