getprogname,
setprogname — get and set
program name
library “libbsd”
#include
<stdlib.h> (See libbsd(7)
for include usage.)
const char *
getprogname(void);
void
setprogname(const
char *progname);
The
getprogname()
returns a string with the current program name, excluding any directory
component. The function will return NULL if it was
unable to get the program name from any known source.
The
setprogname()
function sets the current program name, stripping any directory component
prefix. The function will keep a reference to the passed string pointer, so
it must not be freed or modified while these functions might be called.
The implementations on most BSDs will try to
initialize the program name at program startup time, and
libbsd will try to infer it from various known
sources depending on the target system. But it is not a portable assumption
that the program name will be set without calling
setprogname(),
so portable programs should always call it after starting up.
The setprogname() and
getprogname() functions first appeared in
NetBSD 1.6, FreeBSD 4.4,
DragonFly 2.1 and OpenBSD
5.4.
