Memory Functions and Macros


Detailed Description

This is a group of memory management macros and functions. Using macros for working with memory allows several useful things to be implemented. Instrumentation can be performed, different function names or parameters can be rearranged through the macro, and larger blocks of code can be expanded that check whether an allocation is even necessary. The phDALLOC family of macros take more arguments than the general purpose phMemcpy/phMemmove/phCalloc/phMalloc/phRealloc macros. These arguments are used to check how large the memory is and whether more/less memory needs to be allocated and can prevent the call to the memory allocation system.
