    I want to read a file and from some location i need to copy the contents and write into another file.
    Oldfile.txt contents,

    Now while reading a file i need to get some location of line say ABC990;..... and from this line i want to copy contents into another file (till EOF) say Newfile.txt.

    Anyone help me out ASAP. I am a new to file handling in C.
    Thanks in advance.

    fgets() will read a line from a file up to and including the linefeed:

    FILE *in,*out;
    char buf[100];  /* adjust for longest expected line */
    in=fopen("test.txt","r") /* "rt" on Dos/Win */
      /* do something with the line in buf */

    Thanks for your reply,
    Instead of write statment, if i do
    fputs(buf, out); => it also writes all data from input file to output file till EOF.

    How can I get the line location?
    For this there is one file is created called (STOP.txt), if this file exists, then get the line which is just read and copy all contents from that line till EOF into output file.

    Please Help me out.
