Say that I have a strange character group that I want to find in a binary file. I wanted to use something like this:
(define needle (list->string (map integer->char (list #xab #xcd #xef)))) (define needle-offset (call-with-input-file "big_binary_blob.bin" #:mode 'binary (λ (p) (regexp-match-positions (regexp needle) p)))) The "regexp-match-positions" returns #f (even though I know that needle is in there, I put it there). Is there a better way to go about this? The binary blob is about 100 MiB or so, if that helps. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
