STRSTR(3)                  BSD Programmer's Manual                   STRSTR(3)


     strstr, strcasestr - locate a substring in a string


     #include <string.h>

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

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


     The strstr() function locates the first occurrence of the NUL-terminated
     string little in the NUL-terminated string big.

     The strcasestr() function is similar to strstr() but ignores the case of
     both strings.

     If little is an empty string, big is returned; if little occurs nowhere
     in big, NULL is returned; otherwise a pointer to the first character of
     the first occurrence of little is returned.


     memchr(3), strchr(3), strcspn(3), strpbrk(3), strrchr(3), strsep(3),
     strspn(3), strtok(3)


     The strstr() function conforms to ANSI X3.159-1989 ("ANSI C89").
