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 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.
