Subject: pipe.2: SYNOPSIS: Fix incorrect prototype
X-Git-Tag: man-pages-5.12~32

pipe.2: SYNOPSIS: Fix incorrect prototype

A function declarator with empty parentheses, which is not a
prototype, is an obsolescent feature of C (See C17 6.11.6.1), and
doesn't mean 0 parameters, but instead that no information about
the parameters is provided (See C17 6.5.2.2).
