Recovering Matrix from a file.

Hello, so i've this program that scan and print the matrix from a file. anyways the program i have works with normal matrix i mean Square matrix but now i want to make a manual matrix i mean i've to enter the number of lines/columns and then i call the lines and columns in the main.
So the program below explains the situation

Code:

---

int recuperation (int t[][20], char *nomFichier){
    int nbElement=0 ,i,j,nbElement2=0;
    FILE *fp;
    fp=fopen(nomFichier,"r");
    if(fp!=NULL)
    {


        fscanf(fp,"%d\n",&nbElement);
        fscanf(fp,"%d\n",&nbElement2);
        if(nbElement && nbElement2)
        {
            for(i=1;i<=nbElement;i++)
            {
              for(j=1;j<=nbElement2;j++)
              {
                fscanf(fp,"%d",&t[i-1][j-1]);
              }


            }
        }
    }
    else
        printf("\n Fichier vide \n");
    return nbElement;;
}

---

You see the return? nbElement that's the number of lines but i want to return the number of columns too, which is nbElement2.
Because later in main() i've to call this function by typing:
l= recuperation(t,txtfile)
but i can't call the columns since i returned only 1 value.
Hope that you got what i mean, thanks.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
 
#define MAX_ROWS 20
#define MAX_COLS 20
 
bool recuperation(int t[][MAX_COLS], const char *nomFichier, int *rows, int *cols) {
    FILE *fp = fopen(nomFichier, "r");
 
    *rows = *cols = 0;
 
    if (!fp) {
        printf("\n Fichier vide \n");
        return false;
    }
 
    fscanf(fp, "%d%d", rows, cols);
 
    if (*rows <= 0 || *rows > MAX_ROWS || *cols <= 0 || *cols > MAX_COLS) {
        fclose(fp);
        printf("\nNumber of rows or columns out of range\n");
        return false;
    }
 
    for (int r = 0; r < *rows; r++)
      for (int c = 0; c < *cols; c++)
        fscanf(fp, "%d", &t[r][c]);
 
    fclose(fp);
    return true;
}
 
int main() {
    int t[MAX_ROWS][MAX_COLS];
    int rows, cols;
    if (!recuperation(t, "myfile", &rows, &cols)) {
        printf("Could not read file\n");
        exit(EXIT_FAILURE);
    }
   
    for (int r = 0; r < rows; r++) {
      for (int c = 0; c < cols; c++)
          printf("%2d ", t[r][c]);
      printf("\n");
    }
 
    return 0;
}
