    fflush

    I have a program running, which is fflush'ing data in
    with the following sentance

    while ( fgets( output, sizeof output, stdin ) !=EOF )

    now i want to make a client program which start this server program and send a char this this server.. through fflash or something like that



    if i just start the server it waits for input, and as soon as i write eg "this is a test" it starts to check the char

    how do start the program and send a char like this is a test.

    is there any tutorials or something like that

    Do you want to redirect input to your program?

    program.c:
    Code:
    #include <stdio.h>
    
    int main(void) {
        int c;
    
        while((c = getchar()) != EOF) putchar(c);
    
        return 0;
    }
    file.ext:
    Code:
    This is some text.
    Hello, World!
    Code:
    C>program <file.ext
    This is some text.
    Hello, World!
    C>
    To redirect the program's output (ie, stdout) to a file, use the > character.
    Code:
    C>program <file.ext >output.ext
    C>type file.ext
    This is some text.
    Hello, World!
    C>
    The same redirection symbols work under Linux.
