Usage:

  • SCREEN and image handles in use cannot be freed without error! Change screens or fonts before freeing the handle from memory!
  • The actual value of the handle is only important if it fails to return a value in the range specified. A bad return value may create errors!


Handle Functions:

Valid LONG handle returns are less than -1. Failed _LOADIMAGE handle values of -1, zero or positive values are invalid.
