You need the format to be a const char*. "r+b", not r+b.

Code: Select all

typedef struct NewStruct
{
    int a;
    int b;
    char c[20];
} NewStruct;

NewStruct myStruct;
FILE *g_DATAMAPFILE;

NewStruct * pMyStruct = &myStruct;


int SaveDataMap()
{
    g_DATAMAPFILE = fopen("Level.txt", "r+b"); // fopen error fixed
    if(g_DATAMAPFILE == NULL) {return 1;}
    fwrite(pMyStruct, sizeof(*pMyStruct), 1, g_DATAMAPFILE);
    fclose(g_DATAMAPFILE);
    return 0;
   
}

void init()
{
    pMyStruct->a = 20;

    strcpy(pMyStruct->c, "String");
    if(!SaveDataMap()){ExitGame();}
}

Oh thanks! I was trying to figure out why it said i couldnt use w lol thanks! I must have over looked it.

Having trouble figuring out how to save and load from an array of structs... Here is my code.

I changed it a couple of times to try different things and nothing worked. Here is the last thing I tried.

Edit: I got it to work using a for loop, but how do I do it without a loop?
