Introduce getprogname(3) and setprogname(3) library calls. These get and set __progname, respectively. Discussed on: -arch (Feb 2001), -audit Reviewed by: -audit Approved by: kris Obtained from: (mostly) NetBSD 2001-05-15 23:41:01 +00:00

Do not use __progname directly (except in [gs]etprogname(3)). Also, make an internal _getprogname() that is used only inside libc. For libc, getprogname(3) is a weak symbol in case a function of the same name is defined in userland. 2002-03-29 22:43:43 +00:00			`#include "libc_private.h"`
