.Sh DESCRIPTION
|
|
These functions all live in the
|
|
.Pa strings.h
|
|
header file.
|
|
Except for
|
|
.Fn ffs ,
|
|
they operate on strings.
|
|
.Fn index ,
|
|
.Fn rindex ,
|
|
and
|
|
.Fn strcasecmp
|
|
need nul-terminated strings.

.St -isoC-99 ,
|
|
.Xr bstring 3
|
|
for functions that operate on strings that are not nul-terminated, and
|
|
.Xr bitstring 3
|
