function for allocating memory for string array

[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

What do you mean by conflicts? I see a bunch of undeclared functions
here. Just look at the compiler messages and fix the problems one by one.

#include <stdlib>

Here is missing a ``.h`` suffix.

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);

Where is `nscenes` coming from? And you should pay attention how the
types are declared. You assign `char ***` return value from
`Memory2DStr()` to `unsigned char ***` typed `arr_scenes`.

for (i = 0; i < C; i++) {
array = calloc(R,sizeof(char*));
if(array == NULL) { // Memory for the Col

C++ comments are not allowed in ANSI C. Some compilers understand them
but if you want to write portable code you should steer clear of them.

fprintf(stderr, "Failed to allocate memory\n");

The declaration of `fprintf()` lives in `stdio.h`.

Wrong group!
Anyway, there is no need to reinvent the wheel, there are many array
libraries for C...
