strstr



PURPOSE

Locates a substring.

LIBRARY

Standard C Library (libc.a)

SYNTAX

#include <string.h>

char *strstr (string1, string2);
char *string1, *string2;

DESCRIPTION

The strstr function returns a pointer to the beginning of the first occurrence
of string2 in string1.  The strstr function does not consider the null
character (\0) that ends string2 in the matching process.

If string2 does not appear in string1, strstr returns NULL.

EXAMPLE

The following example locates the string "hay" in the string ""needle in a
haystack"".

  #include <string.h>

  char *string1 = "needle in a haystack";
  char *string2 = "hay";
  char *result;

  result = strstr (string1,string2);
     /* Result = a pointer to "hay" */
