Interface LinuxLibc

All Superinterfaces:
CLibrary, com.sun.jna.platform.linux.LibC, com.sun.jna.platform.unix.LibCAPI, com.sun.jna.Library, com.sun.jna.platform.unix.Reboot, com.sun.jna.platform.unix.Resource
public interface LinuxLibc extends com.sun.jna.platform.linux.LibC, CLibrary
Linux C Library. This class should be considered non-API as it may be removed if/when its code is incorporated into the JNA project.

      static final com.sun.jna.NativeLong SYS_GETTID

  • Method Details

    • getutxent

      LinuxLibc.LinuxUtmpx 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 LinuxLibc.LinuxUtmpx on success, and NULL on failure (which includes the "record not found" case)

    • gettid

      int gettid()
      Returns the caller's thread ID (TID). In a single-threaded process, the thread ID is equal to the process ID. In a multithreaded process, all threads have the same PID, but each one has a unique TID.
      Returns:
      the thread ID of the calling thread.

    • syscall

      com.sun.jna.NativeLong syscall(com.sun.jna.NativeLong number, Object... args)
      syscall() performs the system call whose assembly language interface has the specified number with the specified arguments.
      Parameters:
      number - sys call number
      args - sys call arguments
      Returns:
      The return value is defined by the system call being invoked. In general, a 0 return value indicates success. A -1 return value indicates an error, and an error code is stored in errno.
