[$] Glibc wrappers for (nearly all) Linux system calls
The GNU C Library (glibc) is a famously conservative project. In the past,
that conservatism created a situation where there is no way to directly
call a number of Linux system calls from a glibc-using program. As glibc
has relaxed a bit in recent years, its developers have started to
reconsider adding wrapper functions for previously inaccessible system
calls. But, as the discussion shows, adding these wrappers is still not as
straightforward as one might think.
