Library

Overview

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.
