    NtCreatePort
    ============

    Creates a LPC port object. The creator of the LPC port becomes a server
    of LPC communication

    PortHandle - Points to a variable that will receive the
        port object handle if the call is successful.

    ObjectAttributes - Points to a structure that specifies the object s
        attributes. OBJ_KERNEL_HANDLE, OBJ_OPENLINK, OBJ_OPENIF, OBJ_EXCLUSIVE,
        OBJ_PERMANENT, and OBJ_INHERIT are not valid attributes for a port object.

    MaxConnectionInfoLength - The maximum size, in bytes, of data that can
        be sent through the port.

    MaxMessageLength - The maximum size, in bytes, of a message
        that can be sent through the port.

    MaxPoolUsage - Specifies the maximum amount of NonPaged pool that can be used for
        message storage. Zero means default value.

    ZwCreatePort verifies that (MaxDataSize <= 0x104) and (MaxMessageSize <= 0x148).

    =============

    Creates a port connected to a named port (cliend side).

    PortName - Points to a structure that specifies the name
        of the port to connect to.

    SecurityQos - Points to a structure that specifies the level
        of impersonation available to the port listener.

    ClientView - Optionally points to a structure describing
        the shared memory region used to send large amounts of data
        to the listener; if the call is successful, this will be updated.

    ServerView - Optionally points to a caller-allocated buffer
        or variable that receives information on the shared memory region
        used by the listener to send large amounts of data to the
        caller.

    MaxMessageLength - Optionally points to a variable that receives the size,
        in bytes, of the largest message that can be sent through the port.

    ConnectionInformation - Optionally points to a caller-allocated
        buffer or variable that specifies connect data to send to the listener,
        and receives connect data sent by the listener.

    ConnectionInformationLength - Optionally points to a variable that
        specifies the size, in bytes, of the connect data to send
        to the listener, and receives the size of the connect data
        sent by the listener.

/*++

    NtCreateSection
    ===============

    Creates a section object.

    SectionHandle - Points to a variable that will receive the section
        object handle if the call is successful.

    DesiredAccess - Specifies the type of access that the caller requires
        to the section object. This parameter can be zero, or any combination
        of the following flags:

        SECTION_QUERY       - Query access
        SECTION_MAP_WRITE   - Can be written when mapped
        SECTION_MAP_READ    - Can be read when mapped
        SECTION_MAP_EXECUTE - Can be executed when mapped
        SECTION_EXTEND_SIZE - Extend access
        SECTION_ALL_ACCESS  - All of the preceding +
                              STANDARD_RIGHTS_REQUIRED

    ObjectAttributes - Points to a structure that specifies the object s attributes.
        OBJ_OPENLINK is not a valid attribute for a section object.

    MaximumSize - Optionally points to a variable that specifies the size,
        in bytes, of the section. If FileHandle is zero, the size must be
        specified; otherwise, it can be defaulted from the size of the file
        referred to by FileHandle.

    SectionPageProtection - The protection desired for the pages
        of the section when the section is mapped. This parameter can take
        one of the following values:

        PAGE_READONLY
        PAGE_READWRITE
        PAGE_WRITECOPY
        PAGE_EXECUTE
        PAGE_EXECUTE_READ
        PAGE_EXECUTE_READWRITE
        PAGE_EXECUTE_WRITECOPY

    AllocationAttributes - The attributes for the section. This parameter must
        be a combination of the following values:

        SEC_BASED     0x00200000    // Map section at same address in each process
        SEC_NO_CHANGE 0x00400000    // Disable changes to protection of pages
        SEC_IMAGE     0x01000000    // Map section as an image
        SEC_VLM       0x02000000    // Map section in VLM region
        SEC_RESERVE   0x04000000    // Reserve without allocating pagefile storage
        SEC_COMMIT    0x08000000    // Commit pages; the default behavior
        SEC_NOCACHE   0x10000000    // Mark pages as non-cacheable

    FileHandle - Identifies the file from which to create the section object.
        The file must be opened with an access mode compatible with the protection
        flags specified by the Protect parameter. If FileHandle is zero,
        the function creates a section object of the specified size backed
        by the paging file rather than by a named file in the file system.
