A good reason to require such thing to be documented in the related man page.
Before I realized in 2005, that e.g. wordexp() did not work on OpenSolaris
because it depended on a non-distributable hacked version of ksh88, verry few
people did realize that a libc function other than e.g. system() or popen()
would call fork.
