size_t
strspn(const char *s, const char *charset);

size_t
strcspn(const char *s, const char *charset);

char *
strstr(const char *big, const char *little);

char *

DESCRIPTION

The string functions manipulate strings terminated by a null byte.

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

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

SEE ALSO

bstring(3), index(3), rindex(3), stpcpy(3), strcasecmp(3), strcat(3), strchr(3), strcmp(3), strcpy(3), strcspn(3), strerror(3), strlen(3), strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3)

STANDARDS

The strcat(), strncat(), strchr(), strrchr(), strcmp(), strncmp(), strcpy(), strncpy(), strerror(), strlen(), strpbrk(), strspn(), strcspn(), strstr(), and strtok() functions conform to ISO/IEC 9899:1990 ("ISO C90").

"I liken starting one's computing career with Unix, say as an undergraduate, to being born in East Africa. It is intolerably hot, your body is covered with lice and flies, you are malnourished and you suffer from numerous curable diseases. But, as far as young East Africans can tell, this is simply the natural condition and they live within it. By the time they find out differently, it is too late. They already think that the writing of shell scripts is a natural act."
