Strstr () in emacs lisp?

Question

I want to find a string in another (basically what strstr does in C), and I did not find anything in the elisp manual.

Do I need to overestimate all this, or am I missing something obvious?

Answer 1

Or you can use regular expressions:

 (string-match-p "foo" "barfoo") 3 

or

 (string-match "foo" "barbar") nil 

See Regexp-Search for details.

Answer 2

Lines are sequences. And thus the search will work:

 (search "foo" "in foo-bar") 3
