#include <string.h>
char _ptr64 *strstr64(
const char _ptr64 *s1,
const char _ptr64 *s2);
PARAMETERS
s1 Specifies the character string being searched.
s2 Specifies the substring to be located.
DESCRIPTION
The strstr64( ) 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.
RETURN VALUES
Upon successful completion, the strstr64( ) function returns a pointer to the located string or a
null pointer when the string is not found. When the s2 parameter points to a string having 0
