 NAME    [Toc]    [Back]
      intro - introduction to system calls
 DESCRIPTION    [Toc]    [Back]
      This section describes all of the system calls.  All of these calls
      return a function result.  This result indicates the status of the
      call.  Typically, a zero or positive result indicates that the call
      completed successfully, and -1 indicates an error.  The individual
      descriptions specify the details.  An error number is also made
      available in the external variable errno (see errno(2)).  Note: errno
      is not cleared on successful calls.  Therefore, it should be tested
      only after an error has been indicated.
