GETUSERSHELL(3) BSD Library Functions Manual GETUSERSHELL(3)NAME
getusershell, setusershell, endusershell -- get valid user shells
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
char *
getusershell(void);
void
setusershell(void);
void
endusershell(void);
DESCRIPTION
The getusershell() function returns a pointer to a valid user shell as defined by the system manager in the shells database as described in
shells(5). If the shells database is not available, getusershell() behaves as if /bin/sh and /bin/csh were listed.
The getusershell() function reads the next line (opening the file if necessary); setusershell() rewinds the file; endusershell() closes it.
FILES
/etc/shells
DIAGNOSTICS
The routine getusershell() returns a null pointer (0) on EOF.
SEE ALSO shells(5)HISTORY
The getusershell() function appeared in 4.3BSD.
BUGS
The getusershell() function leaves its result in an internal static object and returns a pointer to that object. Subsequent calls to
getusershell() will modify the same object.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
