Re: read lines from file which gets updated at same time 15 Years Ago by CoolAtt ok will do that. instead of making the program sleep, will it be ok to check everytime in an infinite loop for the following: if fgets is not null -> read & process Re: read lines from file which gets updated at same time 15 Years Ago by CoolAtt ok. plz give an overview. the sequence of steps i mean. is my understanding correct ? while(1){ if fgets == NULL{ sleep clearerr } else read & process string } Re: read lines from file which gets updated at same time 15 Years Ago by Murtan That looks pretty close. Remember that just because fgets() did not return NULL does NOT mean that it read a complete input line. (It is possible for fgets to return with a partial line of data if there is a partial line of data at the end of the file.)

Make sure you plan that the reader might be able to get a 'partial' record from the updater. It is possible that the processor might swap from one app to the other before the record is completely written. For file sharing, look at "FileShare Enumeration" for .Net in MSDN Re: read lines from file which gets updated at same time 15 Years Ago by CoolAtt will implement in C. cant we make the fgets() wait until the updater writes some new line ? Re: read lines from file which gets updated at same time 15 Years Ago by CoolAtt i tried this piece of code: while (1) { fgets(buffer,1024,myfile); printf("%s\n",buffer); } the prob is that wen it reaches the end of file , it keeps on printing the last line. Re: read lines from file which gets updated at same time 15 Years Ago by Salem > the prob is that wen it reaches the end of file , it keeps on printing the last line. You ignore the return result of fgets() You could try detecting that - fgets() returns NULL - then sleeping for a while, in the hope the file will grow - call clearerr() to reset the EOF condition. Re: read lines from file which gets updated at same time 15 Years Ago by Murtan No, you would be MUCH better off sleeping. If you don't sleep the CPU shows 100% utilization and things slow down, including the other program trying to write the data. I would start the sleep at 1 second (1000 ms) and wouldn't reduce it unless the performance required it.
