50The
51.Fn proc_fltset2str ,
52.Fn proc_sigset2str ,
53and
54.Fn proc_sysset2str
55functions respectively convert the fault, signal, and system call sets in
56.Fa fltset ,
57.Fa sigset ,
58and
59.Fa sysset
60to a human-readable name and place the corresponding string in
61.Fa buf .
62.Pp
63Up to
64.Fa buflen
65characters will be placed in
66.Fa buf ,
67including the null terminator.
68If
69.Fa buf
70is not large enough to hold the entire string, then an error
71will be returned.
72.Pp
73The

88.Pp
89The string
90.Fa delim
91will be placed in-between every member of the set.
92It will not come after the last entry in the set.
93.Sh RETURN VALUES
94Upon successful completion, the
95.Fn proc_fltset2str ,
96.Fn proc_sigset2str ,
