Except for .Fn ffs , they operate on strings. .Fn index , .Fn rindex , and .Fn strcasecmp need nul-terminated strings.

p See the specific manual pages for more information.

p See .Xr string 3 for string functions that follow .St -ansiC or .St -isoC-99 , .Xr bstring 3 for functions that operate on strings that are not nul-terminated, and .Xr bitstring 3 for bit-string manipulation macros. .Sh SEE ALSO .Xr bcmp 3 , .Xr bcopy 3 , .Xr bitstring 3 , .Xr bstring 3 , .Xr bzero 3 , .Xr ffs 3 , .Xr index 3 , .Xr rindex 3 , .Xr strcasecmp 3 , .Xr string 3
