Increasing number of rows in 2D c-array - c

Question

Can't increase rows in 2d array, but columns is ok.
#include <stdio.h>
#include <stdlib.h>
it is working:
void increasecolumn(int ** mas, int* n, int m){
for (int i = 0; i < m; i++){
int* tmp = realloc(mas[i], sizeof (*mas[i]) * ((*n) + 1));
if (tmp){
mas[i] = tmp;
}
}
(*n) = (*n) + 1;
}
but increasing rows failed
void increaserow(int ** mas, int n, int* m){
int ** tmp = realloc(mas, sizeof(*mas) * ((*m) + 1));
if (tmp){
mas = tmp;
for (int i = 0; i < 1; i++){
mas[(*m) + i] = malloc(sizeof(*mas[(*m) + i]) * n);
}
}
(*m) = (*m) + 1;
}
int main(int argc, char * argv[]) {
int n = 3; // columns
int m = 2; // rows
int** mas = malloc(m*sizeof(*mas));
for(int i = 0; i < m; i++){
mas[i] = malloc(n*sizeof(*(mas[i])));
}
for(int i = 0; i < m; i++){
for(int j = 0; j < n; j++){
mas[i][j] = 0;
printf("%d ", mas[i][j]);
}
printf("\n");
}
printf("\n");
increasecolumn(mas, &n, m);
for (int i = 0; i < m; i++){
mas[i][n-1] = 1;
}
increaserow(mas, n, &m); // problem is here
for (int j = 0; j < n; j++){
mas[m-1][j] = 0;
}
for(int i = 0; i < m; i++){
for(int j = 0; j < n; j++){
printf("%d ", mas[i][j]);
}
printf("\n");
}
system("pause");
return 0;
}
I use this answer Resizing 2D Arrays in C like an example, something wrong.
