    Question Malloc for an Array of Structs

    Hey all,

    I was trying to malloc an array of structs and i always gets an error for incompatible types
    Here's part of my code:
    Code:
    #define MAX_COMMANDS 50
    
    typedef struct {
    	SpecType Type;
    	RangeSpec Range;
    	char Command;
    	String Text;
    } EditCommandType;
    
    EditCommandType CArray[MAX_COMMANDS];
    
    CArray = (EditCommandType *)Malloc(50 * sizeof(EditCommandType));
    What am i doing wrong??
    Thanks

    If you have defined it as an array, you already have the memory allocated. You can do arrays or malloc, never both. And malloc starts with a lowercase m.

    i have it with an uppercase M because I have my own function.
    The problem is that when I try to access an array location i.e. CArray[1] it gives me an error that it cannot access the memory location

    malloc or Malloc -- if you define EditCommandType CArray[50], you have the memory and must not try to allocate more.

    Also, CArray[1] is a struct, so you should deal with CArray[1].Type, CArray[1].Range, etc.
