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

NAME

     strstr, strcasestr - locate a substring in a string

SYNOPSIS

     #include <string.h>

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

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

DESCRIPTION

     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.

SEE ALSO

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

STANDARDS

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