Main() function; inside an external function in an external file

Question

I would like to know if there is a possibility to include/call/return the function int main(){ within a case(x){ in an external file, to form a loop. I am developing an old game, and I am creating several files and calling them to the source code main. c to keep organized. I will try to explain with the codes below:

Here I would be during the game, but if player X won, he would have the option to return to the navigation menu.

//main.c
#include "functions/playerX.c"

int main(){
unsigned char game[3][3] = {'~','~','~','~','~','~','~','~','~'};

tralha(linha,coluna,game);

printf("O X seleciona a casa");
scanf("%hd", casa);

playerX(casa,game,option);

}

In case Player X typed 1 he would return to the beginning of the function int main(){ making a vicious loop, so there was no excessive repetition of code.

//playerX.c
void playerX(short unsigned int x){

switch(x){
case 1:
main();
break;
}
}

If there’s no possibility, there’s some resource I might be using to do something similar?
