GETUSERSHELL(3) MachTen Programmer’s Manual GETUSERSHELL(3)

NAME
getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS
char *
getusershell(void)

void
setusershell(void)

void
endusershell(void)

DESCRIPTION
The getusershell() function returns a pointer to a legal user shell as
defined by the system manager in the file /etc/shells. If /etc/shells is
unreadable or does not exist, getusershell() behaves as if /bin/sh and
/bin/csh were listed in the file.

The getusershell() function reads the next line (opening the file if nec-
essary); setusershell() rewinds the file; endusershell() closes it.

FILES
/etc/shells

DIAGNOSTICS
The routine getusershell() returns a null pointer (0) on EOF.

SEE ALSO
shells(5)

HISTORY
The getusershell() function appeared in 4.3BSD.

BUGS
The getusershell() function leaves its result in an internal static ob-
ject and returns a pointer to that object. Subsequent calls to
getusershell() will modify the same object.
