GETUSERSHELL(3-BSD) RISC/os Reference Manual  GETUSERSHELL(3-BSD)



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 does not exist, the two standard system shells
     /bin/sh and /bin/csh are returned.

     getusershell reads the next line (opening the file if neces-
     sary); setusershell rewinds the file; endusershell closes
     it.

FILES
     /etc/shells

DIAGNOSTICS

     or error.
