Interface SystemB

All Superinterfaces:

CLibrary, LibCAPI, Library, Reboot, Resource, SystemB

public interface SystemB
extends SystemB, CLibrary

System class. This class should be considered non-API as it may be removed if/when its code is incorporated into the JNA project.

Method Details

getutxent

SystemB.MacUtmpx getutxent()

Reads a line from the current file position in the utmp file. It returns a pointer to a structure containing the fields of the line.

Not thread safe

Returns:

a SystemB.MacUtmpx on success, and NULL on failure (which includes the "record not found" case)

proc_pidfdinfo

int proc_pidfdinfo(int pid,
 int fd,
 int flavor,
 Structure buffer,
 int buffersize)

vm_deallocate

int vm_deallocate(int targetTask,
 long address,
 long size)
