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.

    • Method Detail

      • 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,
                               java.lang.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.
