Flash With C In Unix

[HannahI 0]

How do I do it?

[yordan 10]

Are you asking how to download Adobe Flashplayer for Linux ? Or are you asking if Flash Player exists for Unix versions other than Linux ?Or are you saying that you want to write down a C program using flash instructions for people having not installed Flash on their Windows PC ?

I mean making a flash in C to work on Unix.

[BCD 1]

For me those three things put together... oh thats almost not possible as my knowledge says.You mean you want to embed flash elements in C language? I haven't seen anyone doing that, may be it requires lots of expertise if possible.May be if you could tell what you are trying to achieve, I would try guessing some alternatives.

What I'm tring to say is that, I want to make a flash on the screen in C; I know it would be possible directly in Unix by having a for loop that clears the screen the prints something.

Ha! Now we start understanding.You don't want an embedded Adobe Flashplayer.
You want to have a flashing light on the user's screen from a C program.
something like

system ("tput rev");printf("											  ");printf("											  ");printf("											  ");printf("											  ");system ("tput sgr0");

Of course, I hope this is to be used on a Unix system. On a Crosoft Winbows I would be curious to see the result of "tput rev" !

Sorry about the grammar. Also, what file is it in?

Huh? In what file is what ?

What file is the system command in?

What file is the system command in?

Have a look at a C language manual, for instance here : https://support1-sgi.custhelp.com/And look for the "system" function :

system FunctionThe contents and mode of execution of the string passed to the system function (4.10.4.5).

The contents of the string should be a command string, as if typed to a normal IRIX shell, such as sh(1). A shell ( sh) is forked, and the string is passed to it. The current process waits until the shell has completed and returns the exit status of the shell as the return value.

Assuming that you know how to program in C, the way to colorize text within a C program is to use ansi escape sequences. See: https://en.wikipedia.org/wiki/ANSI_escape_code

Basically you set up a bunch of defines that you put in a header and include it in any .c files that need color in them.

/* These are the ANSI codes for foreground text colors */
#define ANSI_BLACK "\033[0;30m"
#define ANSI_DRED "\033[0;31m"
#define ANSI_DGREEN "\033[0;32m"
#define ANSI_ORANGE "\033[0;33m"
#define ANSI_DBLUE "\033[0;34m"
#define ANSI_PURPLE "\033[0;35m"
#define ANSI_CYAN "\033[0;36m"
#define ANSI_GREY "\033[0;37m"
#define ANSI_DGREY "\033[1;30m"
#define ANSI_RED "\033[1;31m"
#define ANSI_GREEN "\033[1;32m"
#define ANSI_YELLOW "\033[1;33m"
#define ANSI_BLUE "\033[1;34m"
#define ANSI_PINK "\033[1;35m"
#define ANSI_LBLUE "\033[1;36m"
#define ANSI_WHITE "\033[1;37m"
#define ANSI_RESET "\033[0m"
#define ANSI_BOLD "\033[1m" /* For bright color stuff */
#define ANSI_ITALIC "\033[3m" /* Italic text */
#define ANSI_UNDERLINE "\033[4m" /* Underline text */
#define ANSI_BLINK "\033[5m" /* Blinking text */
#define ANSI_REVERSE "\033[7m" /* Reverse colors */
#define ANSI_STRIKEOUT "\033[9m" /* Overstrike line */


Then you can use these colors like this,

printf ( var, "%s this is red text", ANSI_RED);

This is by no means a really elegant way to do things, if you want something better you would need to write your own colour passer, that itterates over text and extracts color coders and then outputs correctly, the way i achieve this is to have my own output functions that do all this for me. That way i can do somethign like this,

MY_printf ( var, "This is <G26> grey text: );

The MY_printf function iterates over the char * removing the <G26> and replacing it with the correct escape sequence.

here is a nice colour parser.

I'm trying ask what file it is defined in. E.G.

#include <stdio.h>int main() {printf("Hello");}

I'm trying ask what file it is defined in. E.G.

#include <stdio.h>int main() {printf("Hello");}

In order to printf "Hello", the C linker needs some standards subroutines, which are in the file stdio.h (standard input-output subroutines). #include means "please include in my program the routines in stdio.h, so that each function I will call will be defined in stdio.h

Yeah, WHAT FILE IS IT IN?
