File memory copy

Eric · 04-12-2014 05:06 PM

Hello,
today I've discovered that it's impossible to copy content of one file created in memory to another file created in memory. Is that true or I've missed something?

Hi,
Why not?
This should work.
Make sure to set position of the source to 0 before writing.

here's my functions body:

Code:

// files needed to update .pak

    Memc<PakFileData> files;

    PakFileData &pfd=files.New();

    // name

    pfd.name=Program::path_records+_srd.title+L".record";

    // date

    pfd.modify_time_utc.getLocal();

    // start writing to memory

    pfd.file.writeMem();

    // reset the source position to 0

    if(!_file.pos(0))

    {

        if(error) *error=Program::sres_filesave_pos;

        return false;

    }

    // copy from source file to pfd destination without flushing

    if(!_file.copy(pfd.file, -1, false))

    {

        if(error) *error=Program::sres_filesave_copy;

        return false;

    }

    // update .pak

    Bool result=_set->getOwner()->_updatePak(error, files);

The result size of pfd file is 0 smile

Code:

void InitPre()

{

   EE_INIT();

   File a, b;

   a.writeMem();

   b.writeMem();

   a.putStr("test");

   a.pos(0);

   a.copy(b);

   b.pos(0);

   Exit(b.getStr());

}

this works fine

Ok, probably found the cause of my problem. Can this line be called on a second thread? It returns true. The _file is ready to writeMem() and SoundCapture is created. Checked also _half_size - it's fine.

Code:

if(!_file.put(SoundCapture.data(), _half_size))

P.S. I'll write to you PM to upgrade my license.
