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.
