Thread: write funtion and CR/LF issue

here's the point, as the help from TC says:

"On text files, when write sees LF (linefeed) character, it outputs a CR/LF (carriage-return/linefeed)pair"

and here is a little example from my code:

Code:

                 i=0;
	 do
	 {
	    read(fd,&c,1);
	    if(c!='\n' || !eof(fd))
	    {
		x.telefono[i]=c;
		i++;
	    }
	 }while(c!='\n' && !eof(fd));
	 x.telefono[i]='\0';

	 if(strcmp(x.nombre,nom)!=0)
	 {
	    int fd2=open("temp.txt",4);
	    if(fd2<0)
	       fd2=creat("temp.txt",751);
	    else
	    {
	       lseek(fd2,0,2);
	       write(fd2,"\n",1);
	    }
	    write(fd2,&x.nombre,strlen(x.nombre));
	    write(fd2,"|",1);
	    write(fd2,&x.direccion,strlen(x.direccion));
	    write(fd2,"|",1);
	    write(fd2,&x.telefono,strlen(x.telefono));
	    close(fd2);
	 }

so my problem is this:

In the last part (x.telefono), i dont want that the function write automatically put the CR character on my file, so anyone have an idea??

i cant use binary because this practice is about archives with a delimitator structure (thats way i am writing the '|' character).

I tried to fix it not writing the LF character (see code):

Code:

i=0;
	 do
	 {
	    read(fd,&c,1);
	    if(c!='\n' || !eof(fd))
	    {
		x.telefono[i]=c;
		i++;
	    }
	 }while(c!='\n' && !eof(fd));
	 //x.telefono[i]='\0';

but there is not change, it works the same with or without the LF character, thats is why i am confused.

I don't understand what this is supposed to do.

Code:

        read(fd,&c,1);
        if(c!='\n' || !eof(fd))
	{
	    x.telefono[i]=c;
	    i++;
	}

it shure doesn't skip any '\n'

Code:

                 do
	 {
	    read(fd,&c,1);
	    if(c!='\n' || !eof(fd))
	    {
		x.telefono[i]=c;
		i++;
	    }
	 }while(c!='\n' && !eof(fd));

this part is filling x.telefono with the data from the file, telefono is the las part of all my registry, so if a CR is write in the end of the archive it mess it all because when i capture a new registry it "jumps" two lines and my file becomes useless... if you like a can post the full "delete" function i have.
