DESCRIPTION
The string functions manipulate strings terminated by a nul byte.

See the specific manual pages for more information. For manipulating variable length generic objects as byte strings (without the nul byte check), see bstring(3).

Except as noted in their specific manual pages, the string functions do not test the destination for size limitations.

The strcat(), strncat(), strchr(), strrchr(), strcmp(), strncmp(), strcpy(), strncpy(), strcoll(), strerror(), strlen(), strpbrk(), strsep(), strspn(), strcspn(), strstr(), strtok(), and strxfrm() functions conform to ansiC.

The strtok_r() function conforms to p1003.1c-95.

The strerror_r() function conform to p1003.1-2001.
