intro(2)

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.
