Subject: Re: suggestion for improvement to vfork() man page
Date: Tue, 07 Feb 2012 16:50:11 -0500 [thread overview]
Message-ID: <6.2.5.6.2.20120207164707.03c1f410@binnacle.cx> (raw)
+(However, on such systems,
+the preferred standard way of accomplishing the same result is to use
+.BR posix_spawn (3).)
I'm not sure I agree on this. Linux posix_spawn()
calls fork() which for us is undesirable on MMU systems
due to the cost of copying large page tables.
To the extent that we would add support for non-MMU
platforms, we would stick with direct invocation of
vfork() even if the posix_spawn() on those targets
used vfork() instead of fork(). One less #ifdef,
of which we have far too many as it is.
