Returning string from function in c/c++[solved]

Question

I would like to make function which would return char*, I don't think that using malloc is good solution, here is how it looks now:
char* fore(int color){
char* tmp = "\x1b[3_m";
*(tmp + 3) = '0' + color; // color is number up to 9
return tmp;
}

Answer 1

Ok... I found solution
char*func(){
static char buf[] = "string";
return buf;
}

Answer 2

solution for C++ was including string class

any idea how to do it in C?

Answer 3

i don’t know if this is what you want

Answer 4

Not really - I don't want any buffer array, it's solution, but it would be weird in usage - it's meant to just color text

Answer 5

By the way - it's
sprintf(buf, "\x1b[3%dm", c);

Answer 6

you said you wanted to return string. what is string, then?

Answer 7

little edit - this is how it should work...

Answer 8

well, u worte using malloc is not a good solution. anyway. good luck. btw, learn how to free the memory if you use dynamic memory.

Answer 9

Thanks... But using malloc... Well... If I remember right - it keeps allocated memory till end of program, in other words it's same as your solution

Answer 10

in current OSs, it’s fine, even in such small apps. but i meant, it’s good to use malloc-free together

Answer 11

Yeah... But here it's impossible to use free... Maybe I just should make global char array and problem would be solved without errors and allocating too much memory... Still I want to know how it would be possible do it same simple as this:
const char* str(){
return "string";
}

Answer 12

This solution is... Ok... I tried that first... But than it became too chaotic and it's lot writing... So I created external file with enum colors and class style with static function

Answer 13

Yeah, I know, but it's little bit complicated for my knowlage - for example that typedef for void pointer to some function, I don't really get what it does

Answer 14

I don't want to open another thread, I gues you know answer to question if there is one solution for all platforms to be used like getch from conio - I'd like to control my app in terminal/console with arrows, space etc. but I haven't found any multiplatform solution (for unix there is ncursed I think)

Answer 15

And for c++ only?

Answer 16

Some way to get input when any key is pressed for c++ only, I know that I could use Qt for this... But I'm doing it without it, because it's supposed to be easily portable code (I'm doing only "console" application)

Answer 17

Ok, really thanks, I hope I'll find solution

Answer 18

I think I finaly get it - there are several functions which means style, and function __col_print which takes message and some param which is name of function which style I want...
