Help with memory leak (malloc)
- by user146780
I'v followed a tutorial to use OGL tesselaton. In one of the callbacks there is a malloc and it creates a leak every time I render a new frame.
void CALLBACK combineCallback(GLdouble coords[3], GLdouble *vertex_data[4],
GLfloat weight[4], GLdouble **dataOut)
{
GLdouble *vertex;
vertex = (GLdouble *) malloc(6 * sizeof(GLdouble));
vertex[0] = coords[0];
vertex[1] = coords[1];
vertex[2] = coords[2];
for (int i = 3; i < 6; i++)
{
vertex[i] = weight[0] * vertex_data[0][i] +
weight[1] * vertex_data[0][i] +
weight[2] * vertex_data[0][i] +
weight[3] * vertex_data[0][i];
}
*dataOut = vertex;
}
I'v tried to free(vertex) but then the polygons did not render. I also tried allocating on the heap then doing delete(vertex) but then the polygon rendered awkwardly. I'm not sure what to do.
Thanks
