• FreeMem() Frees memory allocated with AllocMem().
• free() Frees memory allocated with malloc().

The following calls get information about available memory:

• AvailMem() Gets information about available memory.
• GetBankBits() Finds out which VRAM bank contains a memory location.
• GetMemType() Gets the type of the specified memory.
• GetPageSize() Gets the number of bytes in a memory page.

The following call reclaims unused memory:

• ScavengeMem() Returns a task's unused memory pages to the system-wide memory pool.

The following call changes the status of memory:

• ControlMem() Grants or revokes write permission to memory, or gives memory to another task.

The following calls deal with private lists:

• AllocMemFromMemList() Allocates memory from a private memory pool.
• FreeMemList() Frees a memory list.
• FreeMemToMemList() Frees a private block of memory.

The following calls allocate and free memory pools.

• AllocMemBlocks() Transfers pages of memory from the system-wide free memory pool.
• AllocMemFromMemLists() Allocates a memory block from a list of memory lists.
• FreeMemToMemLists() Returns a block of memory to a free memory pool.

The following calls find problems with memory.

• CreateMemDebug() Initializes memory debugging package
• DeleteMemDebug() Releases memory debugging resources
• DumpMemDebug()Dumps memory allocation debugging information
• SanityCheckMemDebug()Checks all current memory allocations to make sure all of the allocation cookies are intact
