GETUSERSHELL(3)                      BSD                       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 does not exist,
     the four standard system shells (/bin/sh, /bin/csh, /bin/ksh, and
     /com/sh) are returned.

     getusershell 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 or error.
