Re: C strstr function returns int or char *?

[Erik Steffl <steffl@bigfoot.com>]

  you are probably missing the prototype, if there is no prototype for a
function, it defaults to an integer returning function.

  you might be missing the #include <string.h> line or for some reason
the __P is defined not to put prototype in its place (it depends on
compiler options).

  generally you'll get better answer to programming Qs in programming
related newsgroups/mailinglists/forums.
