SYNOPSIS
#include <stdio.h>
int system (string)
char *string;
DESCRIPTION
system causes the string to be given 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 Manual.
DIAGNOSTICS
system forks to create a child process that in turn exec's
/bin/sh in order to execute string. If the fork or exec
fails, system returns a negative value and sets errno.
