What does fgets return

Active Oldest Votes. The documentation for fgets does not say what you think it does: From my manpage fgets reads in at most one less than size characters from stream and stores them into the buffer pointed to by s.

And later gets and fgets return s on success, and NULL on error or when end of file occurs while no characters have been read.

Improve this answer. Can you explain feof part, why doesn't it print anything. EOF has been reached right? It does not confusingly indicate you are at the end of the file. You do the fgets again, you will get EOF. That's the normal way to test. You continue using fgets until you see it return NULL to end the loop. Got it! I used an if , should've used a while.

Production of polypropylene takes place by slurry, solution or gas phase process, in which the propylene monomer is subjected to heat and pressure in the presence of a catalyst system.

Polymerisation is achieved at relatively low temperature and pressure and the product yielded is translucent, but readily coloured. Polypropylene is generally considered safe for use, but you should still be wary of using plastics more often than you have to. The chemicals found in plastic products are proven to contribute to some cancers. PP is also commonly used for disposable diapers, pails, plastic bottle tops, margarine and yogurt containers, potato chip bags, straws, packing tape and rope.

However, 5 plastic is today becoming more accepted by recyclers. PP is considered safe for reuse. To make a long story short: plastic recycling numbers 2, 4 and 5 are the safest.
