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 indi-
cates 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.
