p See the specific manual pages for more information. For manipulating variable length generic objects as byte strings (without the null byte check), see .Xr bstring 3 .
p Except as noted in their specific manual pages, the string functions do not test the destination for size limitations. .Sh SEE ALSO .Xr bstring 3 , .Xr index 3 , .Xr rindex 3 , .Xr stpcpy 3 , .Xr strcasecmp 3 , .Xr strcat 3 , .Xr strchr 3 , .Xr strcmp 3 , .Xr strcpy 3 , .Xr strcspn 3 , .Xr strerror 3 , .Xr strlen 3 , .Xr strpbrk 3 , .Xr strrchr 3 , .Xr strsep 3 , .Xr strspn 3 , .Xr strstr 3 , .Xr strtok 3 .Sh STANDARDS The .Fn strcat , .Fn strncat , .Fn strchr , .Fn strrchr , .Fn strcmp , .Fn strncmp , .Fn strcpy , .Fn strncpy , .Fn strerror , .Fn strlen , .Fn strpbrk , .Fn strspn , .Fn strcspn , .Fn strstr , and .Fn strtok functions conform to .St -isoC .
