我已經在我的OpenGL項目中實現了Bill Dudney的.Obj model loader,我目前有大量內存泄漏!OpenGLES釋放需要返回的變量
使用儀器,我設法縮小到下面的功能。我認爲這與ptr永遠不會被釋放有關,但我仍然需要在函數結束時返回ptr。
const void * TextureCoordBytes(CFAllocatorRef allocator, const void *value, GLuint *size)
{
// extract the count
GLuint count = ((GLuint *)value)[0];
void *ptr = NULL;
if(1 == count)
{ // a 1D texture
ptr = CFAllocatorAllocate(allocator, sizeof(GLfloat), 0);
((GLfloat*)ptr)[0] = ((TextureCoord1D *)value)->u;
*size = sizeof(GLfloat);
}
else if(2 == count)
{ // a 2D texture
ptr = CFAllocatorAllocate(allocator, 2 * sizeof(GLfloat), 0);
((GLfloat*)ptr)[0] = ((TextureCoord2D *)value)->u;
((GLfloat*)ptr)[1] = ((TextureCoord2D *)value)->v;
*size = 2 * sizeof(GLfloat);
}
else if(3 == count)
{ // a 3D texture
ptr = CFAllocatorAllocate(allocator, 3 * sizeof(GLfloat), 0);
((GLfloat*)ptr)[0] = ((TextureCoord3D *)value)->u;
((GLfloat*)ptr)[1] = ((TextureCoord3D *)value)->v;
((GLfloat*)ptr)[2] = ((TextureCoord3D *)value)->w;
*size = 3 * sizeof(GLfloat);
}
return ptr;
}
有誰知道我丟失的東西在這裏或一種方法,我可以使用free(ptr);
之後它仍然return ptr;
?
