Memory allocating/deallocating using functions

[Sheldon]

Hi,

Can someone tell me how to remove the conflicts here ?

#include <stdlib>
static char*** Memory2DStr(int R, int C);
static void MemoryFreeStr(int C, char*** array);

void main() {
unsigned char ***arr_scenes=NULL;
int R = 15;
int C = 15;

arr_scenes = Memory2DStr(nscenes,2);
MemoryFreeStr(2,arr_scenes);
}

static
char*** Memory2DStr(int R, int C) {
char*** array;
int i;
array = calloc(C,sizeof(char **));
if(array == NULL) {
fprintf(stderr, "Failed to allocate memory\n");
exit(EXIT_FAILURE);
}
for (i = 0; i < C; i++) {
array = calloc(R,sizeof(char*));
if(array == NULL) { // Memory for the Col
fprintf(stderr, "Failed to allocate memory\n");
exit(EXIT_FAILURE);
}
}
return array;
}

static
void MemoryFreeStr(int Col, char*** array) {
int i;
for (i = 0; i < 15; i++) {
free((*array));
}
free(*array);

}

Thanks,
Sheldon

I don't konw what you mean by "conflicts", but you could start by:

- including <stdlib.h> instead of <stdlib>
- include <stdio.h>
- declaring main() properly
- declaring nscenes
- sorting out your "char ***" and "unsigned char ***"

and then you should consider what those unused R and C variables in
main are for.

Of course, you could have got all of that from reading your compiler's
error messages.

void main() {

Continue by getting the return type of main right.

When you've learned those two important lessons, come on back.
