    fgets problem

    I'm opening the /proc/hostname file and reading in the string in that file. But I need to use that string and then append other stuff after it later, but it appears as though there is an newline character after the string. here's my code:

    Code:
    fp = fopen("/thefile", "r");
    fgets(lineBuf, count, fp);
    fclose(fp);
    and if you do a printf directly after that, it prints what is in lineBuf and then go to the next line!? anyone?

    fgets stops if the newline character is encountered. It is included in the string though.

    Do this after your call to fgets:
    if ( ( p = strchr ( lineBuf, '\n' ) ) != NULL ) *p = '\0';

    You find the newline and replace it with a nul.

    i would say yes, since thats what strchr returns.
