Message-ID: <1106691570.41f6c5f250fdc@www.doc.ic.ac.uk> (raw)
I tried to read in a text file and extract the string between (* and *) into a
variable, buff, by using the openfile and read functions in Unix module. But
get an error on compilation.
The code I came up with is as follows:
open Unix;;
let file_reader = openfile "sudent.cd" [O_RDONLY] 0o640;;
let buff = ref "empty";;
let main () =
let file_content = read file_reader !buff 1 5 in
print_int file_content;
print_string !buff;;
main ();
I couldn't work out what went wrong. Can anyone help?!!
