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.

NS_GetMemoryManager
any code, intended to be used exclusively with mozilla 1.8 and above, may use ns_alloc, ns_realloc, and ns_free instead to access the xpcom memory manager's methods.

Core XPCOM functions
ns_newlocalfilethe ns_newlocalfile function creates an instance of nsilocalfile that provides a platform independent representation of a file path.ns_newnativelocalfilethe ns_newnativelocalfile function creates an instance of nsilocalfile that provides a platform independent representation of a file path.ns_reallocreallocates a block of memory using the xpcom memory manager.ns_shutdownxpcomthe ns_shutdownxpcom function terminates use of xpcom in the calling process.nsresultthe nsresult data type is a strongly-typed enum used to represent a value returned by an xpcom function; these are typically error or status codes.
