DESCRIPTION    [Toc]    [Back]

       The strstr() function locates the first occurrence in  the
       string  pointed  to by the s1 parameter of the sequence of
       bytes in the  string  pointed  to  by  the  s2  parameter,
       excluding the terminating null character.

       On  successful completion, the strstr() function returns a
       pointer to the located string or a  null  pointer  if  the
       string  is  not  found.  When the s2 parameter points to a
       string having  0  (zero)  length,  the  strstr()  function
       returns the string pointed to by parameter s1.
