The line should contain the pathname of a valid user shell. If /etc/shells does not exist or is unreadable, getusershell() behaves as if /bin/sh and /bin/csh were listed in the file. The setusershell() function rewinds /etc/shells. The endusershell() function closes /etc/shells. RETURN VALUE The getusershell() function returns NULL on end-of-file. FILES /etc/shells ATTRIBUTES For an explanation of the terms used in this section, see at- tributes(7). +------------------------------------------+---------------+-----------+ |Interface | Attribute | Value | +------------------------------------------+---------------+-----------+ |getusershell(), setusershell(), | Thread safety | MT-Unsafe | |endusershell() | | | +------------------------------------------+---------------+-----------+ STANDARDS None.
