Hi, By reading the manual page of posix_spawn(3), I figured out that some information was outdated following the changes brought by glibc 2.24. Since glibc 2.24, the Linux implementation of posix_spawn has been relying on clone(2) with CLONE_VM and CLONE_VFORK attributes instead of fork(2)/vfork(2). The first patch of the series updates the documentation so that both behaviours (i.e. before and since glibc 2.24) are properly described. The second patch is an attempt to remove an ambiguity when mentioning "fork". Kind regards, Olivier Gayot (2): posix_spawn.3: Document implementation using clone() since glibc 2.24 posix_spawn.3: Clarify by using name of steps rather than syscalls man3/posix_spawn.3 | 31 ++++++++++++++++++++----------- 1 file changed, 20 insertions(+), 11 deletions(-) -- 2.19.1
