The following C functions are new or have been modified for Version 2.3:

Function	Where Documented
All C API entry points beginning with "ns_" have been renamed to begin with "Ns_": The following C API functions have been renamed to be consistent with the naming convention of the remaining C API functions: ns_calloc, ns_free, ns_malloc, ns_realloc, ns_strcopy, and ns_strdup. The old entry points still work for backwards compatibility, but they are considered obsolete.	C Developer's Guide: page 50, page 182, page 214, page 227, page 313, and page 314
