Read until a certain character?

AndreasA · 08-11-2003, 02:57 PM

Is there some easy way to read from a file descriptor until i run into a certain character?

For example if I read the following:
Hello&Bye&

I would want it to stop reading at the & and put 'Hello' or possibly 'Hello&' in the buffer, and at the second run it would read 'Bye.'

what do you mean by second run?

like you want the program to end and when you start it up again it'll do the second word?

What programming language?

In most general terms you either want to read character by character (checking for the &, etc) or read one line at a time and split it afterwards. If it's C/C++ or Perl i might be able to help you.

Cheers,

echo "Hello&Bye&"|sed -e's/&/ /g'
Hello Bye

echo "Hello&Bye&"|cut -d '&' --output-delimiter=" " -f 1,2
Hello Bye

If you are using C you can read the entire string and tokenize it with strtok. If using C++ there is a string tokenizer in the std string class.

I'm writing it in C, and strtok seems to be just what I'm looking for, thank you very much.
