The
.Fn proc_fltset2str ,
.Fn proc_sigset2str ,
and
.Fn proc_sysset2str
functions respectively convert the fault, signal, and system call sets in
.Fa fltset ,
.Fa sigset ,
and
.Fa sysset
to a human-readable name and place the corresponding string in
.Fa buf .
.Pp
Up to
.Fa buflen
characters will be placed in
.Fa buf ,
including the null terminator.
If
.Fa buf
is not large enough to hold the entire string, then an error
will be returned.

.Pp
The string
.Fa delim
will be placed in-between every member of the set.
It will not come after the last entry in the set.
.Sh RETURN VALUES
Upon successful completion, the
.Fn proc_fltset2str ,
