newlines and getc()... i just dont get it.

Hi, I'm getting two spaces instead of just one and this is not good!

The differences occur when there is just a blank line.

So if we had a file:

/* everything is good */
/* everything is good */ 

/* I'm a space ahead of where I am now if you output me with the below code */

Here's the code:

 
	while ( EOF != (inChar = getc(inFile)) ) {
		if ( (column >= options.width) ) {
			if ('\n' != outLine[offset-1] ) { 
				outLine[offset++] = '\n'; 
			}
			fwrite(outLine, sizeof(char), offset, stdout); 
			memset(outLine, '\0', 65535); 
			offset = lastBlank = thereWasASpaceInThisLine = column = 0;
		}

		outLine[offset++] = inChar;
		column = incColumn(&column, inChar, options);

		if ( '\n' == inChar ) {
			thereWasASpaceInThisLine = FALSE;
			column = options.width;
		}
	}

Perhaps... it has to do with the linux newline being 0d0a0d? My application could be incorrectly interpretting that as two newlines. (From looking at the hex, I"m seeing 0d0a0d)

I still can't figure this one out. Is it recommended to just read the file in binary and forget about this '\n' stuff? I just want to output text exactly as how it exists in the file, and the only problem I'm encountering is sometimes it will output 2 new lines where there should only be one.

I cant really understand what are u trying to do. Are u trying to just print what ever there in the file line by line?

If that was the case why dint use fgets. And perhaps can you please explain and post a bit more of code so that i could run it on my machine and see what i get and debug.

fgets/fputs would be easier to read and write a text file.

That looks more like a DOS file which was accidentally edited on Linux (or vice-versa).

Linux would be just 0A
DOS/Win32 would be 0D0A

There are a couple of Linux utilities, dos2unix and unix2dos, which can clean up the line endings and make them more suited to one OS or the other.
