How can a streams module read files?

I have a streams module which runs over IP. When it gets loaded
for the first time, a data file has to be read and data structures
have to be initialised accordignly.
But I'm not able to use open, read calls from inside the module (naturally!).
Any pointers?
Here is the sample code:
int _init(void)
/* open (), read () calls have be inserted here */
return (mod_install(&sample_modlinkage));
}

See 'File I/O from within a driver' thread in this forum for a discussion...

    Long hold on the document in mail and it should give you the open in... option, select adobe reader and the file is now saved locally for viewing even while offline.

    As stated you can't. Even if the compressed data is TV compatible, the container is not. If the file is playback compatible with the QT X Player, you can, of course, play the file on your main system and "mirror" its display to the TV. Unfortunately, this normally means only the video is played back via the TV device. On the other hand, if you convert the MKV content to an TV compatible file (or move the compressed data to an TV compatible container if the data is already TV compatible), then you can mirror the QT X player (with audio) to the TV device in the full screen mode, air play/mirror it from iTunes (or any mobile device), or stream it directly from itunes.
    Basically, what you can do here depends on the compressed data in the MKV file container and how you define "mirroring."

    I am a first-time iPad owner/user. I bought a relative's original iPad. I want to leave the apps on it and add my own pdfs to read. My itunes account is really for my iPod. iTunes message says that if I "Sync" the iPad will be erase, and become like my iPods. If I make a new iTunes account, would the apps be erased when I tried to use it?
    How can I just get my files onto this iPad, and still have the apps that my relative left there for me?
    Thank you.

    iPads sync to 1 computer only.
    All media and apps are tied to the Apple ID that purchased them.
    Without your relatives ID and password, you cannot update any of the Apps.
    I am pretty certain he is also violating Apples terms of service by giving you the apps.

    SWF files are flash files, which are not supported on the iPad : http://www.apple.com/hotnews/thoughts-on-flash/
    If you want to play the file then the iSwifter or Skyfire browser apps might work (they don't work on all flash sites) but you won't be able to download it

    I have just bought a Panasonic Lumix compact camera. Aperture and Preview can't open the RAW files from this camera. Panasonic recommend downloading 'SYLKPIX Developer Studio SE' to save RAW file formats.How can Aperture and Preview read the files?

    Either use 'SYLKPIX Developer Studio SE' to develope the RAW files and to save them in another lossless format like TIFF, or try if Adobe's free DNG Coverter can convert your Lumix RAW files to dng. Then import the dngs. This way, your files will still be RAW files.  This works (most times) for my Lumix FZ28.

  • How can i stream video from mac os x 10 using roku to my tv?

    how can i stream video from mac os x 10 using roku to my tv?

    Welcome to Apple Support Communities
    OS X can't write in NTFS disks. If you want to write in NTFS drives, you have to use a third-party app like Paragon for NTFS, being this application the best one to write in those disks.
    Another option is to format the external disk in FAT32 or exFAT on a PC, so you will be able to read and write in Macs and PCs without having to use third-party apps. Do it on a PC and copy the files of your external drive to the internal disk first

  • How can i upload a image file to server by using jsp or servlet.

    Hi,
    I m gurumoorthy. how can i upload a image file to server by using jsp or servlet without using third party API. pls anyone send me atleast outline of the source code.
    Pls send me anyone.
    Regards,
    Gurumoorthy.

    I'm not an applet programmer so I can't give you much advice there.
    If you want to stream the file from the server before it's entirely uploaded, then I don't believe you can treat it like a normal file. If you're just wanting to throw it up there and then listen to it, then you can treat it like a normal file.
    But again, I'm not entirely certain. You might be able to stream the start of the file from the server while you're still uploading the end of it, but it probably depends on what method you're using to do the transfer.

  • How can I stream mms on my Mac?

    I've been going around this one for years. How can I stream mms on my Mac?
    With Mountain Lion, my previous solutions were broken. (Cocoa JT and ASFRecorderX)
    Now, I haven't been able to even stream mms videos (wmv). How the heck do I do it now? Should I just use Windows via Fusion?

    The problem with VLC is that it does not recognize formats automatically.
    You have to select among the many file formats, codecs and file save format to capture a stream.
    The previous apps I used automatically reconized formats and just streamed them.

    how  can i stream audio to ipad from video playing on the apple tv using air play?

    I don't know what AppleTV can handle as far as bit rate is concerned, but increase the bit rate as high as it will let you. You are taking DV which is 25Mb/s and compressing it. If you're making an H.264, you should get great results needing no more than 6Mb/s. Bear in mind, the higher the bit rate, the larger the file size.

    Sara,
    It is not working. I wish to decline in having the pdf pack. How can I give up this purchase? I definitely do not want the Adobe PDF Pack anymore.
    Who do I have to contact or what do I need to do to cancel this purchase?

    How can I combine different pdf files in one?
    created by Sara.Forsberg in Adobe PDF Pack - View the full discussion 
    Hi Flávia,
    Adobe PDF Pack is an online subscription--it definitely allows you to combine several files into one PDF file. For more information about PDF Pack, see Reliably Create PDFs, Convert PDFs, & Merge PDFs Online | Adobe PDF Pack. If you don't have the full version of Acrobat, this is a great solution for combining PDF files.
    However, if you're using Acrobat (not Adobe Reader), you combine files by following these steps:
    Open a PDF file that you want to add pages to.
    Click the Pages pane on the Tools panel (on the right side of the application).
    Click Insert From File, and choose the file that you want to combine with the PDF that you opened in step 1.
    Make any changes necessary in the Insert Pages dialog box--these settings determine where the new file will be inserted.
    Click OK.
    Please let me know how it goes.
    Best,
    Sara

    Either of these should help.

    Or search 'disk size' in the App Store.
    Be carefull with what you delete & have a backup BEFORE you start, you may also want to reboot to try to free any memory that may have been written to disk.
