Memory reporting
each reporter implements a collectreports function which takes a nsimemoryreportercallback argument; for each measurement the reporter must pass in several values, including: a path (which identifies the report); an amount (the most important thing); a unit (most commonly bytes, but sometimes a unitless count or percentage); a description of what is measured.
... see the nsimemoryreporter documentation and nsimemoryreporter.idl for full details.

The new nsString class implementation (1999) - Archive of obsolete content
our minimalistic nsimemoryagent interface is just rich enough to support the nsstring idiom, and could be extended to serve as the general memory allocation idiom.
... here's it's api: class nsimemoryagent : nsisupports { void* new(nsint32 asize)=0; //used for both alloc and realloc void* delete(void* aptr)=0; }; internationalization the new nsstrimpl/nsstring implementation addresses at least two of the primary concerns of our i18n team.

Choosing the right memory allocator
ns_alloc() == nsimemory::alloc() ns_realloc() == nsimemory::realloc() ns_free() == nsimemory::free() nsmemory::clone() (note: not part of nsimemory) see infallible memory allocation for information about how to allocate memory infallibly; that is, how to use memory allocators that will only return valid memory buffers, and never return null.
...these methods convert ns*string to nsimemory allocated, unowned [pruni]char* buffers.

NS_Alloc

NS_Free
