@(#)getusershell.3 6.1 (Berkeley) 11/08/85

C 6 getusershell, setusershell, endusershell - get legal user shells

 char *getusershell() 

 setusershell() 

 endusershell() 

Getusershell returns a pointer to a legal user shell as defined by the system manager in the file /etc/shells . If /etc/shells does not exist, the two standard system shells /bin/sh and /bin/csh are returned.

Getusershell reads the next line (opening the file if necessary); setusershell rewinds the file; endusershell closes it.

/etc/shells The routine getusershell returns a null pointer (0) on EOF or error. All information is contained in a static area so it must be copied if it is to be saved.
