NAME
getusershell, setusershell, endusershell - get legal user shells
SYNOPSIS
char *getusershell()
setusershell()
endusershell()
DESCRIPTION
Getusershell returns a pointer to a legal user shell as defined by the system manager in the file /etc/shells. If /etc/shells is unread-
able or does not exist, getusershell behaves as if /bin/sh and /bin/csh were listed in the file.
Getusershell reads the next line (opening the file if necessary); setusershell rewinds the file; endusershell closes it.
FILES

DIAGNOSTICS
