SYSTEM(3S)      (C Programming Language Utilities)     SYSTEM(3S)



  NAME
       system - issue a shell command

  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.
