As The Linux Programming Interface went to press in August 2010, it was up to date with the then current versions of the Linux kernel (2.6.35), glibc (2.12), and the POSIX.1/Single UNIX Standard (POSIX.1-2008/SUSv4). Because the developers of both the Linux kernel and glibc are committed to maintaining ABI compatibility, virtually all of the details provided in TLPI should remain accurate in the f
