AW: [En-Nut-Discussion] --fgets function question--

[Ernst Stippl]

Hi Raul!

fgets waits for a string (upto the newline char) to arrive.
Have a look at the sample programs: uart.c tcps.c 

in uart.c  you will find the following code sequence:



        /*
         * A bit more advanced input routine is able to read a string 
         * up to and including the first newline character or until a
         * specified maximum number of characters, whichever comes first.
         */
        fputs("\nEnter your name: ", uart);
        fflush(uart);
        fgets(inbuf, sizeof(inbuf), uart);

        /*
         * Chop off trailing linefeed.
         */
        cp = strchr(inbuf, '\n');
        if (cp)
            *cp = 0;

        /*
         * Streams support formatted output as well as printing strings 
         * from program space.
         */
        if (inbuf[0])
            fprintf(uart, "\nHello %s!\n", inbuf);
        else {
            fputs_P(pgm_ptr, uart); 




hope this hels

regards

ernst

Hi to all :
question: does the fgets function when called , does it waits until it
receives data (just like a regular c++ program , that waits for the input)
or if at the exact scan time that the function is called , if theres nothing
it continues the program sequence????

Thanks in advance
