"will return" sounds strange to be.

Normal is "Upon successful completion, the value 0 is returned...".
This is part of what ".Rv -std" expands to.

POSIX says "Upon successful completion, ftruncate( ) shall return 0...".

The POSIX wording is better.  "the value 0" says nothing more than "0",
and "returns" is clearer than "is returned".  Saying "the value 0" is
apparently a hack to give the clause a subject (or is it an object? --
I think the value is the object convoluted to a subject or vice versa).

FreeBSD has a script to adjust the POSIX wording.  It
does s/shall return/returns/.
