6 @deftypefn Supplemental char* strstr (const char *@var{string}, const char *@var{sub})
8 This function searches for the substring @var{sub} in the string
9 @var{string}, not including the terminating null characters. A pointer
10 to the first occurrence of @var{sub} is returned, or @code{NULL} if the
11 substring is absent. If @var{sub} points to a string with zero
12 length, the function returns @var{string}.
