PK_ERROR_code_t      PK_MEMORY_register_callbacks
(
--- received arguments ---
PK_MEMORY_frustrum_t frustrum      --- application's memory handlers
)


This function registers memory allocation and free functions for Parasolid
to use when returning variable length information.


Specific Errors:
     PK_ERROR_memory_not_empty     Data is in process of being returned


This function may be called whenever Parasolid's internal PK memory is empty.

The alloc and free functions are allowed to longjump out of Parasolid in case
of an error, with the same restrictions and requirements as the user
registered error handling function. Otherwise the allocator must return NULL
in the event of an error.

If this function has not been called, or either of the function pointers
given is NULL, Parasolid will default to using the appropriate function
from the standard C run-time-library. The application should ensure that
the two functions thus registered are compatible.
