/* FUNCTION: LVEQNB_Memory */
/* */
/* DESCRIPTION: */
/* This function is used for memory allocation and free. It can be called in */
/* two ways: */
/* */
/* hInstance = NULL Returns the memory requirements */
/* hInstance = Instance handle Returns the memory requirements and */
/* allocated base addresses for the instance */
/* */
/* When this function is called for memory allocation (hInstance=NULL) the memory */
/* base address pointers are NULL on return. */
/* */
/* When the function is called for free (hInstance = Instance Handle) the memory */
/* table returns the allocated memory and base addresses used during initialisation. */
/* */
/* PARAMETERS: */
/* hInstance Instance Handle */
/* pMemoryTable Pointer to an empty memory definition table */
/* InitParams Pointer to the instance init parameters */
/* */
/* RETURNS: */
/* LVPSA_OK Succeeds */
/* otherwise Error due to bad parameters */
