NAME

     getprogname, setprogname — get or set the program name

LIBRARY

     library “libbsd”

SYNOPSIS

     #include <stdlib.h>
     (See libbsd(7) for include usage.)

     const char *
     getprogname(void);

     void
     setprogname(const char *progname);

DESCRIPTION

     The getprogname() and setprogname() functions manipulate the name of the current program.
     They are used by error-reporting routines to produce consistent output.

     The getprogname() function returns the name of the program.  If the name has not been set
     yet, it will return NULL.

     The setprogname() function sets the name of the program to be the last component of the
     progname argument.  Since a pointer to the given string is kept as the program name, it
     should not be modified for the rest of the program's lifetime.

     In FreeBSD, the name of the program is set by the start-up code that is run before main();
     thus, running setprogname() is not necessary.  Programs that desire maximum portability
     should still call it; on another operating system, these functions may be implemented in a
     portability library.  Calling setprogname() allows the aforementioned library to learn the
     program name without modifications to the start-up code.

HISTORY

     These functions first appeared in NetBSD 1.6, and made their way into FreeBSD 4.4.
