Re: File Descriptor and readLine() difficulties

Hello,

I have prototyped open and close and I am using Scott's readline almost
verbatim as an external procedure to my program. I have an interface
process that determines the type of message I have received by reading the
header inside each file. There is a group of 3 programs that read the list
of files, and then opens each file to see if it should process them.

Just for the record: The readline() procedure was intended for EDUCATIONAL PURPOSES ONLY. It was intended to be a simple example that you could learn about IFS programming from. It's up to you to write your own routines that work according to your specifications.

Please don't take readline() and use it unless you are willing to understand how it works and modify it as needed for your purposes. It's not intended to be load-n-go code.

You might want to consider using fgets() which is a system-supplied API that does almost the same thing as readline(), but it's faster and doesn't have any of the problems you describe.
