-FUNCTION
-<<system>>---execute command string

-INDEX

-
-ANSI_SYNOPSIS
-	#include <stdlib.h>
-	int system(char *<[s]>);
-
-	int _system_r(void *<[reent]>, char *<[s]>);
-
-TRAD_SYNOPSIS
-	#include <stdlib.h>
-	int system(<[s]>)
-	char *<[s]>;
-
-	int _system_r(<[reent]>, <[s]>)
-	char *<[reent]>;
-	char *<[s]>;
-
-DESCRIPTION
-
-Use <<system>> to pass a command string <<*<[s]>>> to <</bin/sh>> on
-your system, and wait for it to finish executing.
-
-Use ``<<system(NULL)>>'' to test whether your system has <</bin/sh>>
-available.
-
-The alternate function <<_system_r>> is a reentrant version.  The
-extra argument <[reent]> is a pointer to a reentrancy structure.
-
-RETURNS
-<<system(NULL)>> returns a non-zero value if <</bin/sh>> is available, and
-<<0>> if it is not.
-
-With a command argument, the result of <<system>> is the exit status
-returned by <</bin/sh>>.
-
-PORTABILITY
-ANSI C requires <<system>>, but leaves the nature and effects of a
-command processor undefined.  ANSI C does, however, specify that
-<<system(NULL)>> return zero or nonzero to report on the existence of
-a command processor.
-
-POSIX.2 requires <<system>>, and requires that it invoke a <<sh>>.
-Where <<sh>> is found is left unspecified.
-
-Supporting OS subroutines required: <<_exit>>, <<_execve>>, <<_fork_r>>,
-<<_wait_r>>.
