Module libc/darwin
Darwin-only C interface pieces (audit env row: vars()).
macOS does not export environ through the regular headers; the
sanctioned route is <crt_externs.h>'s _NSGetEnviron(). This module is
only ever imported from a Platform.Macos comptime arm, so the header
include never reaches other platforms' emitted C.
Stability
unstable — a raw C binding that exists to serve exactly one caller:
std/env's vars() on macOS. The public surface is std/env, and this
module follows Darwin rather than a Yo design — _NSGetEnviron is
Apple's sanctioned replacement for the environ symbol std/libc/unistd
binds on other Unixes. Anything else Darwin-only that std/ comes to
need lands here, so the surface is additive-by-demand and not frozen.
Functions
The ADDRESS OF the process environment symbol: returns char *** —
dereference once for the NULL-terminated "NAME=VALUE" array.
Returns: *(*(?(*(char))))
