Allocating Additional Heap Space

If you specify a heap size in the EPPC Target settings panel, the linker creates a default heap of this size. The default heap needs no initialization.

You can create additional heaps by:

• Defining ALLOC_ADDITIONAL_HEAPS equal to 1 in either __ppc_eabi_init.c or __ppc_eabi_init.cpp .

  Doing so causes the stub implementation of AllocMoreHeaps() to be called by the runtime initialization code.

• Implementing the AllocMoreHeaps() stub by calling init_alloc() as many times as desired.

  Each time init_alloc() is called, the heap is expanded by the amount specified.
