    copy file

    I intend to copy file, i'm using function fgets to get each record and then put it into the new file....but......it doesn't work the destination file contains nothing,

    handle=fopen("karyawan.dat","w"); // the destination file

    temporer=fopen("temp.$$$","r"); // the source file

    while(fgets(kodec,53,temporer)!=NULL)

    {fprintf(handle,"%s",kodec);

    }

    by the way......it seems to work...i mean i could exit the program..but when i check the file it's nothing......

    Did you check all those functions for error returns?

    And how is kodec declared.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Should work if its a text file you're trying to copy.
    But if it's a binary file (like a .exe), then it wont work.

    Oh, and the opposite of fgets is fputs, not fprintf
