Does anybody know of an algorithm for detecting weather a file is a text file or not short of reading the the entire file. -+= SAM =+- "the best things in life are free" ARPA: paolucci@snll-arpagw.llnl.gov

Sam asks: >Does anybody know of an algorithm for detecting weather a file is a >text file or not short of reading the the entire file. The obvious answer is: see whether the first 512 bytes contain anything other than ascii graphics (space thru tilde) and whitespace (cr, nl, backspace, control-L). If you don't want to read the whole file, don't read the whole file. Am I misunderstanding your question??? If what you're asking is "does AmigaDOS keep track of file type, so you could do some magic call and find out that it's a text file for certain", then the answer is "no". Unfortunately for those of us who are object-oriented. Or fortunately, from the point of view of those who hate dealing with Macintosh resource forks.
