/* DESCRIPTION: */

/* */
/* 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 */
/* pCapabilities Pointer to the default capabilities */
/* */
/* RETURNS: */
/* LVM_SUCCESS Succeeded */
/* LVM_NULLADDRESS When one of pMemoryTable or pInstParams is NULL */
/* LVM_OUTOFRANGE When any of the Instance parameters are out of range */
/* */
/* NOTES: */
/* 1. This function may be interrupted by the LVM_Process function */
/* 2. The scratch memory is the largest required by any of the sub-modules plus any */
/* additional scratch requirements of the bundle */
