.Sh ALTERNATIVES
Some functions have different prototypes depending on the BSD where they
originated from, and these various implementations provided are selectable
at build-time.
.Pp
This is the list of functions that provide multiple implementations:
.Bl -tag -width 4m
.It Fn strnvis 3
.It Fn strnunvis 3
.Nx
added
.Fn strnvis 3
and
.Fn strnunvis 3
but unfortunately made it incompatible with the existing one in
.Ox
and Freedesktop's libbsd (the former having existed for over ten years).
Despite this incompatibility being reported during development (see
http://gnats.netbsd.org/44977) they still shipped it.
Even more unfortunately
.Fx
and later MacOS picked up this incompatible implementation.
.Pp
Provide both implementations and default for now to the historical one to
avoid breakage, but we will switch to the
.Nx
one in a later release, which is internally consistent with the other
.Xr vis 3
functions and is now more widespread.
Define
.Dv LIBBSD_NETBSD_VIS
to switch to the
.Nx one now.
Define
.Dv LIBBSD_OPENBSD_VIS
to keep using the
.Ox
one.
.El
.Sh DEPRECATED
Some functions have been deprecated, they will emit warnings at compile time
and possibly while being linked at run-time.
