GETUSERSHELL(3) 					     Library Functions Manual						   GETUSERSHELL(3)

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
/etc/shells SEE ALSO
shells(5) DIAGNOSTICS
The routine getusershell returns a null pointer (0) on EOF. BUGS
All information is contained in a static area so it must be copied if it is to be saved. 4.3 Berkeley Distribution November 30, 1988 GETUSERSHELL(3)
