SYNOPSIS

#include <unistd.h>
char * getusershell (void);
void setusershell (void);
void endusershell (void);

DESCRIPTION

The getusershell ();
function returns a pointer to a valid user shell as defined by the system manager in the shells database as described in shells(5). If the shells database is not available, getusershell ();
behaves as if /bin/sh and /bin/csh were listed.

The getusershell ();
function 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

HISTORY

The getusershell ();
function appeared in BSD 4.3

BUGS

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