25 /* */
26 /* DESCRIPTION: */
27 /* This function is used for memory allocation and free. It can be called in */
28 /* two ways: */
29 /* */
30 /* hInstance = NULL Returns the memory requirements */
31 /* hInstance = Instance handle Returns the memory requirements and */
32 /* allocated base addresses for the instance */
33 /* */
34 /* When this function is called for memory allocation (hInstance=NULL) the memory */
35 /* base address pointers are NULL on return. */
36 /* */
37 /* When the function is called for free (hInstance = Instance Handle) the memory */
38 /* table returns the allocated memory and base addresses used during initialisation. */
39 /* */
40 /* PARAMETERS: */
41 /* hInstance Instance Handle */
42 /* pMemoryTable Pointer to an empty memory definition table */
43 /* InitParams Pointer to the instance init parameters */
44 /* */
45 /* RETURNS: */
46 /* LVPSA_OK Succeeds */
47 /* otherwise Error due to bad parameters */
