I have a problem when i use memset in my constructor.

This is my source:
Code:
Image::Image(int Width,int Height) {
    memset(data,0,Width*Height*sizeof(u32));
    width=Width;
    height=Height;
    x=0;
    y=0;
    origx=0;
    origy=0;
    swizzled=0;   
}

data is:
Code:
u32 * data


When i use gdb it said that it crashes by the memset function.

What do i wrong?

data is a pointer and it looks like there is no memory allocated.
so, before you can use memset you have to malloc some memory to the pointer.

Learn C/C++, then code on PSP... These forums aren't for basic code questions, there are PLENNNTTTY of forums for that.

I know how to code c++ and this isn't my first thing op psp.

This is just the kind of mistake i often do. (use memset instead of malloc)
