       strstr - locate a substring

SYNOPSIS    [Toc]    [Back]

       #include <string.h>

       char *strstr(const char *haystack, const char *needle);

DESCRIPTION    [Toc]    [Back]

       The  strstr() function finds the first occurrence of the substring nee-
       dle in the string haystack.  The terminating `\0'  characters  are  not
       compared.

RETURN VALUE    [Toc]    [Back]

       The  strstr()  function	returns a pointer to the beginning of the substring,
 or NULL if the substring is not found.

BUGS    [Toc]    [Back]

       Early versions of Linux libc (like 4.5.26) would  not  allow  an  empty
       argument.  Later  versions  (like  4.6.27)  work  correctly, and return
       haystack when needle is empty.
