STRSTR(3)						   BSD Library Functions Manual 						 STRSTR(3)

NAME

     strstr, strcasestr -- locate a substring in a string

LIBRARY

     Standard C Library (libc, -lc)

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.

RETURN VALUES

     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.

EXAMPLES

     The following sets the pointer ptr to the "Bar Baz" portion of largestring:

	   const char *largestring = "Foo Bar Baz";
	   const char *smallstring = "Bar";
	   char *ptr;

	   ptr = strstr(largestring, smallstring);

SEE ALSO

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

STANDARDS

     The strstr() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
