NAME
       intro - introduction to system calls

DESCRIPTION
       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 avail‐
       able in the external variable (see errno(2)).  Note: is not cleared  on
       successful  calls.   Therefore, it should be tested only after an error
       has been indicated.
