getusershell, setusershell, endusershell − get legal user shells
#include <unistd.h>
char *getusershell(void);
void setusershell(void);
void endusershell(void);
The getusershell() function returns the next line from the file /etc/shells, opening the file if necessary. 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.
The getusershell() function returns a NULL pointer on end-of-file.
