pointer to an array of structures

[opendep]

hi..
I am trying to pass an array of structures to a function. my code is

mainObject *scene[10];
void open_callback(int control_id)
{
char *temp_filename = (char*)malloc(255*sizeof(char));
printf("\n Enter the filename : ");
fgets(temp_filename,255,stdin);
temp_filename[strlen(temp_filename)-1] = ' \0 ' ;
open_file(temp_filename, scene);
}

void open_file(char *FileName, mainObject *scene[10])
{
for(int file_count=0; file_count<10; file_count++)
{
scene[file_count] = new mainObject[file_size];
for(int j=0; j< file_size; j++)
{
(scene[file_count]+j)->pos.x = X;
(scene[file_count]+j)->pos.y = Y;
(scene[file_count]+j)->pos.z = Z;
(scene[file_count]+j)->colour.r = R;
(scene[file_count]+j)->colour.g = G;
(scene[file_count]+j)->colour.b = B;
(scene[file_count]+j)->colour.a = A;
(scene[file_count]+j)->renderActive = active;
(scene[file_count]+j)->size = 1.0;
}
}
}

where mainObject is

typedef struct
{
float r,g,b,a;
}color_s ;
typedef struct
{
float x,y,z;
}position_s ;
typedef struct
{
position_s pos;
color_s colour;
float size;
unsigned int renderActive;
}mainObject ;


Execution results in an exception. This may work if i pass a pointer to scene[10]. Can anyone help me with the syntax for this or identify the problem with my code in case its different from the one i assume...

Any help would be greatly appreciated. Thanks a lot

regards,
AM

mainObject *scene[10];
void open_callback(int control_id)
{
char *temp_filename = (char*)malloc(255*sizeof(char));
printf("\n Enter the filename : ");
fgets(temp_filename,255,stdin);
temp_filename[strlen(temp_filename)-1] = ' \0 ' ;
open_file(temp_filename, scene);
}

void open_file(char *FileName, mainObject *scene[10])

There are several problems in this code. One is that you never free temp_filename inside open_callback(). That's a leak.

Then there this:

mainObject *scene[10];

This is an array to 10 scene pointers. I assume each of these pointers points to something. They do, don't they?

If you really meant an array of 10 scene structures, you have to code:

mainObject scene[10];
 

Then you pass this array to a function:

void open_file(char *FileName, mainObject *scene) 
 

and probably should have another argument for the nunmber of elements in tha array.

You mioght reas this article. It addresses your problems.
