getusershell(3) [freebsd man page]

GETUSERSHELL(3) 					   BSD Library Functions Manual 					   GETUSERSHELL(3)

NAME
getusershell, setusershell, endusershell -- get valid user shells LIBRARY
Standard C Library (libc, -lc) 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. SEE ALSO
nsswitch.conf(5), shells(5) HISTORY
The getusershell() function appeared in 4.3BSD. 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. BSD
