        SYNTAX

        #include <stdio.h>

        int system (string)
        char *string;


        DESCRIPTION

        System gives string to sh(1) as input, as if the string had been
        typed as a command at a terminal.  The current process waits
        until the shell has completed, then returns the exit status of
        the shell.


        FILES

        /bin/sh


        SEE ALSO

        exec(2).
        sh(1) in the User's Reference for the DG/UX System.


        DIAGNOSTICS

        System forks to create a child process that in turn execs /bin/sh
        in order to execute string.  If the fork or exec fails, system
        returns a negative value and sets errno.
